摘要

为了提高认知用户的信噪比，提出了一种基于最优极化接收(OPR)的认知无线电方案。这种基于opr的方案不会对许可用户产生额外的干扰。仿真结果表明，在不增加认知用户发射功率的情况下，基于opr的认知接收机与传统认知接收机相比，信噪比最多可提高30dB以上。

A SINR improving scheme based on optimal polarization receiving for the cognitive radios

A scheme based on optimal polarization receiving (OPR) is proposed for the cognitive radios to improve the signal to interference and noise ratio (SINR) of the cognitive user. This OPR-Based scheme will not produce extra interference to the licensed user. The simulation results show that without increasing the transmitting power of the cognitive user, the cognitive receiver with OPR-Based scheme can improve the SINR by over 30dB at most compared with the traditional cognitive receiver.
