Carrier frequency synchronization is critical to the quality of signal reception in OFDM systems. This paper presents an approximate maximum-likelihood (ML) carrier frequency offse...
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...
We proposed a pre-compensation method combining two wireless communication schemes, TDD(Time Division Duplex) whose forward and reverse links use the same frequency, and the coher...
— In an OFDM system, channel estimation can be considered as sampling the time-frequency response of the channel through a number of known pilot symbols placed across the time-fr...
This paper analyzes the influence of time-varying cyclic delay diversity (TV-CDD) on the channel fading correlation properties in orthogonal frequency division multiplexing (OFDM) ...
