常見例句雙語例句The set-tree block is coded independently to improve the anti-BER(bit error rate).樹塊之間獨立進行編碼,以提高系統(tǒng)抗誤碼能力。A new method of unitary space-time constellation, which can improve the influence on block error rate by fast fading, is designed based on a systematic method.在系統(tǒng)化酉空時星座設計方法的基礎上,提出了一種抗信道快變的酉空時星座設計方案。Computer simulation shows the block error rate of unitary space-time modulation increases with the decreasing of autocorrelation of channel coefficients in a block time.通過計算機仿真分析發(fā)現酉空時碼的誤碼率隨著信道衰落系數自相關函數的減小而惡化,且隨分組長度增大而加深惡化。 返回 block error rate
