载波分辨多址接入（CRMA）被引入作为具有被赋予自干扰消除（SIC）的无线电的无线局域网中的信道接入的方法。CRMA在单个信道中操作，并且包括使用SIC来尝试允许多个并发传输中的一个成功，而不是使所有冲突传输失败。因此，大多数信道竞争回合导致成功的无冲突传输。分析了CRMA的吞吐量，并与CSMA、CSMA/CA、CSMA/CD在采用优先级分配时的吞吐量进行了比较。该分析表明，CRMA可以提供更好的吞吐量比其他方法由于使用SIC。
Carrier Resolution Multiple Access (CRMA) is introduced as an approach for channel access in wireless local area networks with radios endowed with self-interference cancellation (SIC). CRMA operates in a single channel and consists of using SIC to try to allow one of multiple concurrent transmissions to succeed, rather than having all colliding transmissions fail. As a result, most channel-contention rounds result in successful collision-free transmissions. The throughput of CRMA is analyzed and compared with the throughput of CSMA, CSMA/CA, and CSMA/CD when priority acknowledgments are used. This analysis shows that CRMA can provide much better throughput than the other approaches thanks to the use of SIC.
