Abstract—Accurate integer frequency offset (IFO) estimation is crucial for OFDM systems, especially in the presence of frequency-selective fading and residual timing offset (RTO). For existing(More)
This study analyses the achievable cooperative diversity order of the distributed linear convolutional space-time coding (DLC-STC) scheme for time–frequency asynchronous cooperative networks. The authors first prove that perfect time or frequency synchronisation is impractical for cooperative networks with multiple relays serving multiple destinations even(More)
