Abstract: A method including transmitting a binary vector from a source node to a relay node and receiving a signal vector at the relay node. The method also includes compressing the signal at the relay node by multiplying the signal with a matrix using probabilities and converting output probabilities from the multiplying into retransmission signal amplitudes, the signal amplitude depending not only on a probability of a bit but on a transmission power constraint at the relay node. The method also includes transmitting, by the relay node, estimates of information from the source node to a destination node.

Abstract translation: 一种方法，包括从源节点向中继节点发送二进制向量并在中继节点处接收信号向量。 该方法还包括通过使用概率将信号与矩阵相乘来压缩中继节点处的信号，并将输出概率从乘法转换为重发信号幅度，信号幅度不仅取决于比特的概率，而且取决于发射功率约束 在中继节点。 该方法还包括由中继节点发送从源节点到目的地节点的信息估计。
