Abstract | This paper proposes an efficient implementation structure for the wideband multi-beamforming network in a beamspace adaptive array for wideband signals. The filter coefficients of the beamforming network are represented as sum-of-powers-to-two coefficients (SOPOT) and are implemented using the multiplier block technique. The SOPOT representation allows the coefficients to be implemented as limited number of adders and shifters without any multiplications. The redundancy in the SOPOT coefficients is further removed by the multiplier block technique to yield minimum adder realization. Design results show that significant reduction in hardware complexity can be obtained by the proposed structure as compared with the conventional direct form implementation. |
