Full-adaptive-weigh module intelligent antenna receiving method and device

An all adaptive-weigh-module weight update device for array antenna is composed of antenna array, RF channel, digital wave beam shaping unit, despreading-descrambling unit, error calculation unit, weight calculation unit and weight choosing unit. Its method includes front-end RF treating, weighting summerizing, conjugate multiplying with PN code, sending the resultant data and reference data to weight update module, choosing system weight for next period, and updating weight. Its advantages are high update effect and optimal received signal.
