Abstract

The work is related to the use of error correction coding and adaptive equalization as an aid to Maximal Ratio Combining (MRC) in order to improve bit error rate(BER)s of received signals in wireless channels with fading characteristics. Several modulation schemes are used in the transmission in Gaussian, multipath Rayleigh and Rician fading channels. The work adopts a few error correction codes and Least Mean Square (LMS) adaptive filter blocks as part of a MRC set-up and is tested under SNR variation between -10 to 10 dB in Gaussian and multipath slow fading channels. The results generated justify the use of the coding and adaptive equalizer block as an aid to the MRC setup.
