    • Systems and methods for demodulating and decoding signals on a multi-path data channel using a pilot signal and at least one additional signal as a demodulation reference. One embodiment includes a method in which a pilot signal is used to demodulate and decode an additional signal, and then both the pilot signal and the additional signal are used to demodulate and decode a data traffic signal. A receiver receives a data traffic signal, a rate indicator signal and a pilot signal. The pilot signal is used as a demodulation reference for the rate indicator signal. After the rate indicator signal is demodulated and decoded, this signal is re-encoded and compared to the received rate indicator signal and used in combination with the pilot signal as a demodulation reference for the demodulation and decoding of the data traffic signal and to estimate SNR for power control purposes.
    • 用于使用导频信号和至少一个附加信号作为解调参考在多路数据信道上解调和解码信号的系统和方法。 一个实施例包括使用导频信号来解调和解码附加信号的方法,然后使用导频信号和附加信号对数据业务信号进行解调和解码。 接收机接收数据业务信号,速率指示符信号和导频信号。 导频信号用作速率指示信号的解调参考。 在速率指示信号被解调和解码之后,将该信号重新编码并与接收的速率指示符信号进行比较,并与导频信号组合使用,作为数据业务信号的解调和解码的解调参考,并估计SNR 用于电源控制目的。
