Uplink Capacity of Cellular Networks with United Cooperative in MIMO Channel

The performance and relations between base stations (BS) and mobile terminal (MT) of hybrid cooperation in cellular communication networks is investigated. Through studying the per-cell achievable uplink ergodic capacity of time-division linear cellular networks with MT-BS hybrid cooperation, a computational expression for the achievable rate of OAF combining with multi-cell processing in MIMO channel is derived and the performance of hybrid collaborations in MIMO channels is verified by simulations. Moreover, the simulation results in MIMO flat fading channels with different system parameters show that the macro-diversity gains through multi-cell decode is independent with MTs collaboration but can be linear superposition. However, high interference from adjacent cells weakens the effect of MTs cooperation in hybrid collaboration systems.
