A New Receiver for 802.11b Spread Spectrum System
This paper proposed a joint DC offset estimation and equalize algorithm. The simulation results show that our proposed algorithm can improve the performance of the 802.11b system, compared to the original receiver, there is 1 dB gain at 1% BER. Further, a sign LMS is applied in proposed algorithm to reduce the complexity and just lost only 0.2 dB performance.
