Digital Beam Forming Based on PDLMS Algorithm and Its Implementation Using FPGA

A new digital beam forming (DBF) method is proposed. It combines the parallel delay LMS (PDLMS) algorithm and the field programmable gate array (FPGA). To realize the adaptive digital beam forming module in hardware, VHSIC hardware description language(VHDL) is used to implement the algorithm in FPGA. Some simulations and analyses of hardware resource verify the feasibility and results show that the method is easy to be realized and has a simple structure.
