OFDM Carrier Synchronization Based on Time-Domain Channel Estimates
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...

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...

Coherent Detection Method with Compensation at Transmitter in Time Division Duplex System
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...

Synchronization Signal Design for OFDM Based On Time-Frequency Hopping Patterns
— 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...
