Abstract: In this paper,we design a 16 uniform circular array beamforming device based on the least squares SLC- LSCMA algorithm based on the linear subspace constrained least squares cma high stability and rapid convergence for the foundation.The design of the complete beam-forming that is based on the SLC-LSCMA algorithm is completed by plural,time-multiplier and accumulators,which uses less resources and faster than the traditional algorithm.The beamforming device uses hardware description language of Verilog HDL,and wires on the QUARTUS Ⅱ 8.0.Finally the beamforming device is downloaded to the Altera’s EP2C35F672C6,and its timing simulation can be run properly in the 50 MHz clock frequency.This design can be widely used in mobile communication and satellite communications.
