BER analysis using Pilot Contamination Mitigation Technique over Weibull Fading in Massive MIMO System

Each base station (BS) is equipped with M (unlimited) antennas serving K (large but finite) users. Further, we let τ (pilot length) be an arbitrary but small value. Pilot contamination results from the re-use of the same set of pilot sequences in the different cells of the system. To mitigate the underline problem in Massive MIMO system, pre-established algorithm (APA) is reviewed and bit error rate is estimated over Weibull fading scenario using APA algorithm. The numerical result shows significant improvement in BER and Spectral efficiency with increasing fading severity.
