协作通信在中继节点之间可以共享资源，提高目的节点的译码性能方面显示出巨大的优势。然而，由于低信号强度或高干扰，中继被认为是不可靠的，其中中继仅传输消息的一部分。为了解决这个问题，在这项工作中，块处理部分传输（PT），这使得中继将源信息划分为小块，并计算消息的可靠性信息。在目的地，相关的空间接收方案被设计为联合解码多个信息副本。其动机是即使每个中继可能不能完全正确地解码消息，中继仍然可以改善目的地的解码。给出了继电保护不可靠时PT端到端中断概率的计算公式。仿真结果表明，所提出的策略可以提供一个显着的改善传统的策略与不可靠的继电器。
The cooperative communications show the great advantage on the relays that can share their resource to improve the decoding of destination. However, relays are considered not reliable due to a low signal strength or high interference, where the relays only transmit a fraction of the message. To solve this problem, in this work, the block processing are implemented in partial transmission (PT), which allows the relays to divide the source information into small blocks and calculate the reliability information of the message. In the destination, a correlated spatial reception scheme is designed to jointly decode several information copies. The motivation is that even if each relay may not decode the message completely correct, the relay can still improve the decoding of destination. This paper formulates the end-to-end outage probability of PT with unreliable relays. Simulation shows the proposed strategy can provide a significant improvement over the conventional strategies with unreliable relays.
