What is Pilot Symbol Assisted Modulation Analysis about?

This paper analyzes pilot symbol assisted modulation (PSAM) for mitigating the effects of rapid fading in mobile communications channels. PSAM involves periodically transmitting known pilot symbols that the receiver uses to estimate the fading channel. Previous work on PSAM lacked rigorous analysis. This paper provides a solid analytical basis for PSAM by deriving closed-form expressions for bit error rate in BPSK and QPSK modulation and a tight upper bound on symbol error rate for 16QAM modulation. It also
