中文摘要：
研究了蜂窝无线通信系统中联合协作传输的性能以及用户协作与基站协作之间的关系。在时分的线性部署蜂窝无线系统中，通过研究MIMO信道条件下基站、用户联合协作方式的单个小区可达上行各态历经速率，给出了MIMO信道中多基站联合解码与终端OAF协作联合模式下的可达速率的计算方法，并通过仿真对MIMO信道下联合协作方式性能进行验证。通过仿真MIMO平坦衰落信道条件下系统参数变化的系统性能，分析得出MIMO信道下多基站联合解码（宏分集）与终端协作性能的线性叠加关系，而，临近小区强干扰将会严重削弱终端与基站联合协作时终端协作的作用。
英文摘要：
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.
