Abstract: In recent years there has been significant interest in the area of Hardware-based Genetic Algorithms (HGA) implemented using a Field Programmable Gate Array (FPGA). This paper presents a hardware-based genetic optimiser applied to adjusting an adaptive antennae receiver. The proposed architecture employs a combination of pipelining and parallelisation to achieve significant speedups over software implementation. The proposed HGA is implemented on a prototyping board with a Xilinx Virtex-E FPGA and reaches a speedup factor of more than 500 when compared to the software implementation.

Keywords: hardware-based genetic algorithms; adaptive antennae arrays; field programmable gate arrays; FPGA; smart antennae receivers; pipelining; parallelisation; speedups; genetic optimiser; embedded systems.
