决定速率 meaning in Chinese

decision speed

A simulation and modeling mechanism is studied and proposed for multirate transmission protocol . based on the wlan that adopts ofdm transmission technique , we first assumed that the small - scall fading and multipath in ofdm sub - channel is rayleigh , and large - scale path loss could be described by bi - linearity model , and then we analyzed the rationality
基于采用ofdm传输技术的wlan ，我们假设ofdm子信道的小尺度衰落服从rayleigh分布，路径损耗可以用双线性模型描述，并对假设的合理性进行了分析，将决定速率切换的误帧率等物理层性能参数和媒质控制协议有机地结合在一起，对多速率传输建模进行了有意的探索。
