Abstract
Wireless link in mobile cellular communication system is experienced by large and small scale fading. Since the link is Non Line of Sight (NLOS), therefore, severely affected by multipath fading. Adaptive equalizer is a widely used technique to neutralize the effect of multipath fading. In this paper, Frequency Domain Adaptive Filer (FDAF) and Least Mean Square (LMS) algorithms are used to combat the effect of multipath fading for 16-QAM and QPSK modulated wave and the results are shown using constellation diagram and bit error rate (BER). Finally, a comparison is made between two algorithms in contexts of process time, mean BER, variance of BER and circuit complexity.
