Abstract:
A method for processing a multi-carrier signal for decoding, wherein the multi-carrier signal includes two or more spread spectrum signals, the method comprising:filtering the multi-carrier signal with a first filter having a bandwidth greater than a bandwidth of any one of the spread spectrum signals; quantizing the filtered signal to generate discrete time samples; and processing one or more of the spread spectrum signals received through the first filter, wherein the processing of each spread spectrum signal includes filtering the discrete time samples with a discrete time filter to provide filtered samples, wherein the discrete time filter has a bandwidth matched to a bandwidth of the particular spread spectrum signal being processed, scaling the filtered samples with a scaling factor, quantizing the scaled samples, measuring a quantity related to an amplitude of the quantized samples, and adjusting the scaling factor in accordance with the measured quantity.
