Collaborative communication produces high power gain, if the frequency and phase synchronization is achieved. In this paper a novel architecture is proposed for a collaborative communication system in the presence of AWGN and frequency offsets. The mathematical expressions are derived and verified through simulation for received power and bit error rate (BER) of the system. It is analyzed that using this collaborative communication model, the significant power gain and reduction in BER can be achieved even though the system is with imperfect frequency synchronization. The analysis of the model is performed using the parameters of off-the-shelf products. The analysis revealed that power gain decreases and BER increases as the frequency offsets (errors) are increases.
