Abstract

We propose a cooperative transmission scheme that uses Hurwitz-Radon space-time code for the relays which help the source to transmit signals to the destination, the full utilization here is that the destination utilizes the broadcast symbols from the source. We present the 2 transmit antennas case in detail because of its simplicity and high data rate. Analysis and simulations show that the proposed scheme achieves full diversity order of 3. The maximum likelihood receiver is also derived and the combining scheme is shown to be very simple.

본 논문에서는 신호를 소스에서 목적지로 전송하는 것을 도와주는 중계기에 Hurwitz-Radon space-time 부호를 사용한 협력통신을 제안한다. 전송안테나가 2개인 시스템이 간단하고 고속의 데이터 율을 제공하기 때문에 보다 자세히 설명한다. 해석과 시뮬레이션은 제안한 시스템이 최대 다이버시티 계수 3을 획득하는 것을 증명한다. 또한, ML 수신기를 수식적으로 유도하고 결합 지법이 아주 간단한 것을 볼 수 있다.
