Abstract
Direct sequence spread spectrum (DSSS) system needs some anti-jam algorithms for communication when strong interference exists. Both Normalized least mean square (NLMS) algorithm in time domain and anti-jam algorithm based on FFT in frequency domain are widely used for the excellent performance and small hardware costs. This paper implemented the two algorithms on FPGA and researched their system performances and hardware costs, finally some useful guides for later system design were given.
