Data‐assisted channel estimation and performance analysis for two‐way amplify‐and‐forward relay networks with M ‐ary frequency shift keying modulation

Approximate Gibbs algorithm for blind data detection in two‐way relay networks

“…The authors of [11] investigated channel estimation and data detection under unknown non‐reciprocal doubly selective fading channels. [12] proposed a method for channel estimation and symbol detection in TWRN with frequency shift keying signalling. In [13], the authors developed a joint estimator of the CFO and channel response for an OFDM‐based TWRN.…”
