CFO/Channel estimation algorithms for space-time block coded orthogonal frequency division multiplexing wireless relay networks without using cyclic prefix of OFDM

This study presents a simple technique, which is used to estimate both channel state and carrier frequency offset (CFO) in decode-and-forward relay systems, where coded orthogonal frequency division multiplexing is employed without cyclic prefix. On the basis of the least-square criterion, we derive...
