    • An improved receiver and method estimate one or more parameters, such as amplitude and signal-to-noise ratio, of a received signal, such as an M-QAM or q-ASK signal. The amplitude of an M-QAM signal is estimated based upon known or ascertainable phase information regarding a plurality of transmitted symbols. The amplitude of a q-ASK signal is estimated based upon known or ascertainable magnitude information regarding a plurality of transmitted symbols. In another embodiment, the amplitude of an M-QAM or q-ASK signal is estimated based on statistical knowledge of the amplitude of the transmitted symbols. Other embodiments estimate amplitude, noise power, and signal-to-noise ratio of a received signal utilizing second-order and fourth-order moments of received samples, a maximum likelihood searching process, or a Kurtosis estimation process.
    • 改进的接收机和方法估计诸如M-QAM或q-ASK信号的接收信号的一个或多个参数,例如振幅和信噪比。 基于关于多个发送符号的已知或可确定的相位信息来估计M-QAM信号的幅度。 基于关于多个发送符号的已知或可确定的幅度信息来估计q-ASK信号的幅度。 在另一个实施例中,M-QAM或q-ASK信号的振幅基于所发送符号的幅度的统计知识来估计。 其他实施例使用接收样本的二阶和四阶矩,最大似然搜索处理或峰度估计过程来估计接收信号的幅度,噪声功率和信噪比。
