Capacity Calculation for Collaborative Communication with Imperfect Phase Synchronization, AWGN and Fading in Sensor Networks

Collaborative communication produces high power gain and significantly mitigates the fading if both frequency and phase synchronization are achieved. In this paper, a procedure of the capacity calculation for collaborative communication system with imperfect phase synchronization that includes the influence of noise and Rayleigh fading is proposed, modeled, theoretically analyzed and simulated. The exact formula for channel capacity as a function of channel parameters and the number of collaborative nodes is derived. It was confirmed that using collaborative communication, the capacity of the network can be increased and energy consumption can be reduced. Key-Words: Collaborative communication, Channel capacity, Waveform channel, Noise and fading.
