Research and Design of Beamforming Device of SLC-LSCMA Algorithm Based on FPGA

Abstract:

In this paper,we design a uniform circular array beamforming device of 16 yuan 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 the SLC-LSCMA algorithm 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 Alteras EP2C35F672C6, and its timing simulation can be run properly in the 50MHz clock frequency. This design can be widely used in mobile communication and satellite communications.
