High-speed LMS Equalizer for Spread Spectrum System Based on FPGA

摘要：

To confront the ISI caused by multipath in spread spectrum system,we proposed a hardware architecture of LMS equalizer based on FPGA using parallel processing, which greatly increased the number of iterations in a limited period, and accelerated the convergence of the algorithm. At the same time, the multiplier and the divider was optimized by using the internal hardware multiplier. Simulation results proved that the scheme almost had the same performance compared with the software result with high speed and less hardware consumption.
