Telecommunications receiver for demodulation of multichannel received signal

摘要

The provision of time control systems for individual teeth of circuit ensures separation of spread spectral components The comb type receiver (112) comprises a number of teeth (122,124,126, 128). Each tooth comprises a demodulator (402) for demodulating the beam of a signal with multiple channels, and a time tracking circuit (404) for controlling the time position of the tooth as a function of the time position of the beam. A state of weak detected spread delay, and the positions of two adjacent teeth are controlled to prevent the convergence of two or several teeth about a common time position. By maintaining the time difference of the teeth, the diversity of the channels is used by the comb type receiver in a weak spread delay state to improve the performance of the receiver.
