Abstract

We studied the performance of a two-user time reversal multiple input single output scheme combined with the shifted transmission technique in a variable rate back-off scenario, called shifted time reversal (TR), that minimizes both intersymbol interference and multiuser interference. We compare the bit error rate performance of the shifted TR scheme to both full-rate TR and full back-off TR schemes and demonstrate its superiority to shifted zero forcing scheme when the guard interval is larger than one.

두명의 사용자를 위한 무선 통신에서 심볼 간 간섭 및 다중 접속 간섭을 최소화하는 유동적인 전송률 back-off 적용 지연 time reversal (TR) 기법의 성능을 평가하였다. 지연 TR 기법의 성능을 기존 full-rate TR과 full back-off TR의 성능과 비교하였으며, guard interval이 1보다 큰 경우 비트오차율 측면에서 지연 TR 기법의 성능이 full-rate TR이나 full back-off TR보다 우수함을 확인하였다.
