This document outlines my proposal for my thesis research project entitled "Adaptive Beamforming Using FPGA Accelerators". In this project I propose building an FPGA accelerator for adaptive beamforming applications using phased array radar systems.
The thesis will begin by reviewing adaptive beamforming algorithms including least mean squares (LMS) filter algorithms such as constant modulus algorithm (CMA), normalized least mean squares (NLMS), recursive least squares (RLS) filter algorithms such as fast affine projection algorithm (FAPA), multiple beamforming techniques such as minimum variance distortionless response (MVDR) beamformer along with fast Fourier transform (FFT) techniques such as split-radix FFT.
I will then propose using these algorithms within an FPGA accelerator framework that takes advantage of both high level synthesis tools such as SystemC AMS extensions or Vivado HLS along with hand coded RTL Verilog design language.
The proposed FPGA accelerator design will consist of two main components; a host processor that controls data flow through the system along with FPGA blocks that perform mathematical operations required by adaptive beamforming algorithms.
Finally I will implement these designs on Altera Cyclone V FPGAs using simulation tools such as Modelsim or Altera Quartus II along with hardware prototyping platforms such as Altera DE1 or DE5 boards.

addcontentsline{toc}{chapter}{Introduction}
Phased array radar systems use multiple antennas that allow them to electronically steer directional beams over a wide range without physically moving antennas.
These systems consist of antenna elements that produce signals that are combined using complex weighting factors called "beamformers" which produce radiation patterns or beams.
By changing these weightings in real time it is possible to electronically steer these beams quickly over large areas.
The objective of this thesis project is to create an FPGA based adaptive beamforming system that uses various adaptive beamforming algorithms including least mean squares (LMS) filter algorithms such as constant modulus algorithm (CMA), normalized least mean squares (NLMS), recursive least squares (RLS) filter algorithms such as fast affine projection algorithm (FAPA), multiple beamforming techniques such as minimum variance distortionless response (MVDR) beamformer along with fast Fourier transform (FFT) techniques such as split-radix FFT.
This thesis will be structured as follows; first we will review various adaptive beamforming algorithms along with hardware implementation techniques including high level synthesis tools such as SystemC AMS extensions or Vivado HLS along with hand coded RTL Verilog design language.
Next we will describe our proposed FPGA accelerator design which consists of two main components; a host processor that controls data flow through the system along with FPGA blocks that perform mathematical operations required by adaptive beamforming algorithms.
Finally we will implement these designs on Altera Cyclone V FPGAs using simulation tools such as Modelsim or Altera Quartus II along with hardware prototyping platforms such as Altera DE1 or DE5 boards.

% Least Mean Squares Filter Algorithms
section*{centerline {Least Mean Squares Filter Algorithms}}
LMS filter algorithms include constant modulus algorithm (CMA), normalized least mean squares (NLMS).
% Constant Modulus Algorithm
subsection*{centerline {Constant Modulus Algorithm}}
The constant modulus algorithm is an LMS type filter algorithm used in radio frequency communications applications where it performs blind equalization by minimizing dispersion caused by multipath propagation effects.
It works by minimizing the dispersion between a received signal $r(n)$ which consists of multipath propagation effects $c(n)$ convolved with transmitted signal $s(n)$ along with additive white Gaussian noise $w(n)$.
$$r(n)=c(n)*s(n)+w(n)label{eqn:cma_1}$$
The CMA performs blind equalization by minimizing dispersion between received signal $r(n)$ while keeping transmitted signal $s(n)$ constant.
$$J=min_{w}sum_{n=1}^{N}|r(n)|^{P}-A^{P}label{eqn:cma_2}$$
where $J$ is cost function that minimizes dispersion between received signal $r(n)$ while keeping transmitted signal $s(n)$ constant.
$P$ is modulus power value where P=1 is linear CMA while P=2 is quadratic CMA.
$A$ is target amplitude value where A=1 if $P=1$ while A=$E[r^{(1)}]$ if $P=2$.
$w$ represents tap weights or coefficients applied onto input signal $x(n)$.
The CMA updates tap weights or coefficients using steepest descent method given by;
$$w(n+1)=w(n)-unabla J(w)label{eqn:cma_3}$$
where $u$ is step size value which determines convergence speed.
$nabla J(w)$ represents gradient vector computed from cost function given by;
$$nabla J(w)=sum_{n=1}^{N}frac{partial}{partial w}[|r(n)|^{P}-A^{P}]label{eqn:cma_4}$$
Expanding equation ref{eqn:cma_4} gives;
$$nabla J(w)=P(|r(n)|^{(P-1)})Re[overline{(r(n))}frac{partial r(n)}{partial w}]^T-A^{(P-1)}(frac{partial A}{partial w})^T$$
Since $frac{partial r(n)}{partial w}=x^*(n)$ then equation ref{eqn:cma_4} becomes;
$$nabla J(w)=P(|r(n)|^{(P-1)})Re[overline{(r(n))}x^*(n)]^T-A^{(P-1)}(frac{partial A}{partial w})^T$$
Since $frac{partial A}{partial w}=0$ then equation ref{eqn:cma_4} becomes;
$$nabla J(w)=P(|r(n)|^{(P-1)})Re[overline{(r(n))}x^*(n)]^T$$
Substituting equation ref{eqn:cma_4} into equation ref{eqn:cma_3} gives;
$$w(n+1)=w(n)-uP(|r(n)|^{(P-1)})Re[overline{(r(n))}x^*(n)]^T$$
Equation ref{eqn:cma_5} represents CMA update rule used for tap weight adaptation given by;
$$w_{i}(n+1)=w_{i}(n)-u(|r_{i}(n)|^{(P-1)})Re[overline{(r_{i}(n))}x_{i}^*(n)]label{eqn:cma_5}$$
% Normalized Least Mean Squares Filter Algorithm
subsection*{centerline {Normalized Least Mean Squares Filter Algorithm}}
The normalized least mean squares algorithm is an extension of LMS algorithm where step size parameter $mu$ used in LMS algorithm updates tap weights or coefficients based on error signal given by;
$$e_{i}(n)=d_{i}(n)-y_{i}(n)label{eqn:nlms_1}$$
is replaced by $mu=frac{mu}{||x_i||}$ where $mu$ depends upon input vector norm given by;
$$||x_i||=sqrt{x_i^*(n)x_i(n)}+epsilon$$
$epsilon$ represents small constant value used for numerical stability.
This results in NLMS update rule given by;
$$w_{i}(n+1)=w_{i}(n)+u(frac{|e_i|}{||x_i||})x_i^*(n)label{eqn:nlms_3}$$
Equation ref{eqn:nlms_3} represents NLMS update rule used for tap weight adaptation where $u=mu E[e_i^* e_i]$ represents step size value which determines convergence speed while $e_i$, $d_i$, $y_i$, $x_i$, represent error signal given by equation ref{eqn:nlms_1}, desired signal, output signal given by equation ref{eqn:lms_y}, input vector given by equation ref{eqn:lms_x}, respectively.
% Recursive Least Squares Filter Algorithms
section*{centerline {Recursive Least Squares Filter Algorithms}}
RLS filter algorithms include fast affine projection algorithm (FAPA).
% Fast Affine Projection Algorithm
subsection*{centerline {Fast Affine Projection Algorithm}}
The FAPA performs blind equalization using recursive least squares filter update rule given by;
$$W(N+1)=W(N)+K(N)[d(N)-X(N)^TW(N)]^H=lambda^{-1}[I-K(N)X(N)^H]W(N)label{eql:fapa_w_update}vspace{-0.25cm}\[0.25cm]
