    • A method of processing digital samples of a signal received at a receiver of a wireless communication system includes monitoring channel conditions and generating a channel indicator including at least one channel parameter by performing at least one of: estimating a channel mobility parameter and comparing it with a threshold; estimating a channel parameter of the energy of the channel outside a predefined temporal window, and comparing it with a threshold; estimating a channel temporal duration parameter and establishing if it meets predetermined criteria; estimating a channel-zero location parameter and establishing if it meets predetermined criteria; estimating a received-signal signal-to-disturbance power ratio, and comparing it to a threshold; estimating an estimated-channel-response signal-to-disturbance power ratio; estimating the degree of non-stationarity of the disturbance at the receiver input; and selecting one of a plurality of processing routines for processing the digital samples based on said channel indicator. Related receivers are also described.
    • 一种处理在无线通信系统的接收机处接收的信号的数字样本的方法包括监视信道状况并通过执行以下中的至少一个来生成包括至少一个信道参数的信道指示符:估计信道移动性参数并将其与 阈; 估计在预定时间窗口之外的信道的能量的信道参数,并将其与阈值进行比较; 估计信道时间持续时间参数并确定它是否符合预定标准; 估计信道零位置参数并确定它是否符合预定标准; 估计接收信号信号与干扰功率比,并将其与阈值进行比较; 估计信道响应信号与干扰功率比; 估计接收机输入干扰的非平稳度; 以及基于所述信道指示符选择用于处理数字样本的多个处理例程之一。 还描述了相关接收机。
