Abstract: PROBLEM TO BE SOLVED: To provide a universal mobile phone system, adopting the WCDMA (wideband code division multiple access) technology or a wireless communication system which adopts the third generation general partnership program. SOLUTION: A code, in an incoming signal from a different source, is specified, using a code adaptive filter to apply cross-correlation on the code. A multiplexer samples signals from P-sets of sources at a rate of a multiple of P, with respect to a chip rate of the code in the incoming signal. The multiplexer applies time multiplex processing to the received signal and supplies the result to one delay line, consisting of N-stages and having P-sets of elements. Each stage stores one sampling value from among P-sets of sources. The selected element of each stage provides an output to an input, corresponding to a dot product summing chain of the code adaptive filter, so as to establish cross-correlation to each incoming signal.

Abstract: A third generation general partnership program radio communication system or a universal mobile telephone system employs a wide band code division multiple access system. The codes in various incoming signals from different sources are identified by cross correlation using a code matched filter. A multiplexer, samples the signals from each of the P sources at P times the chip rate of the codes in the incoming signals. The mutliplexer time multiplexes the received signals and feeds them to single delay line consisting of N stages each having P elements. Each stage will thus store one sample from each of the P sources. A selected element in each stage has an output which feeds a corresponding input of a code matched filter dot-product adder chain to enable a cross-correlation to be established for each incoming signal in turn.
