We propose a reduced complexity maximum likelihood detection technique for coded 16 level differentially encoded amplitude phase shift keying modulation in amplify-and-forward relaying system. This method eliminates the need for pilot symbols for channel estimation, equalization and there is no need for accurate phase tracking at the receiver which is particularly important in Relay aided cooperative...
In this letter, a joint detector for cooperative communication networks is proposed when the destination has limited hardware processing capability. The transmitter sends its symbols with the help of relays. As the destination has limited hardware, only out of signals are processed and the energy of the remaining relays is lost. To solve this problem, a joint preprocessing based detector is...
Information exchange among a group of users is implemented with the aid of fast frequency-hopping M-ary frequency-shift keying multi-way relay (FFH/MFSK MWR). The FFH/MFSK MWR scheme uses two time-slots per symbol for achieving the information exchange, regardless of the number of users involved. During the first time-slot, all the users communicate with a relay based on the FFH/MFSK principles. Then,...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
