| titleOfInvention | Adaptive spread spectrum receiver |
| abstract | Sampled signals SPS of a spread-spectrum received signal are fed to matched filters 12 1 to 12 4, wherein they are despread. A spreading code of a desired signal is used as a despreading code in the matched filter 12 1, and a plurality of spreading codes which are orthogonal to the spreading code of the desired signal and orthogonal to one another are used for despreading in the matched filters 12 2 to 12 4. Outputs x1 to x4 from the filters 12 1 to 12 4 are multipled by weighting coefficients w1 to w4; the multiplied outputs are linearly combined into a combined signal DCS. A coefficient control part 37 is supplied with the signals x1 to x4 to be multiplied by the weighting coefficients w1 to w4 and the combined signal DCS and determines the weighting coefficients w1 to w4 by an algorithm that minimizes the average power of the combined signal DCS under a constraint on the weighting coefficients w1 to w4. |
