Abstract
본 논문에서는 하향 링크 직교 주파수 분할 다중 접속 네트워크에서 길쌈부호의 비트오율에 대한 상계를 유도한다. 비터비 복호기를 사용한다는 가정 하에 네트워크 로드가 작은 경우 라플라시안 복호 메트릭을 사용하는 하향 링크 직교 주파수 분할 다중 접속 네트워크의 비트오율 성능이 가우시안 복호 메트릭을 사용하는 동일 시스템의 비트오율 성능보다 우수하다는 것을 확인할 수 있다. In this paper, union upper bound on convolutional coded bit error rates (BER) is derived for downlink orthogonal frequency division multiple access (OFDMA) networks. According to the numerical results, for the small network loads, the BER performance with Laplacian decoding metric outperforms the BER performance with Gaussian decoding metric under downlink OFDMA networks with Viterbi decoder.
