Ambiguity Function Analysis of OFDM Signals With Pilots and Data Payloads
This paper characterizes two discrete AF formulations for different Doppler regimes, namely the discrete periodic AF (DP-AF) and fast-slow-time AF (FST-AF), and derives closed-form expressions for their expected squared values and proves that attaining the lower bound at non-zero Doppler requires a periodic pilot patte...
