The Performance of Coded Non-Coherent M-ary Orthogonal Keying Based OFDM Systems in a Frequency Selective and Fast Time-Varying
In this paper, we investigate the application of a unipolar Non-Coherent M-ary Orthogonal Keying (NC-MOK) for OFDM system that does not require channel estimation and compare its p...
