ADAPTIVE ARRAY DEVICE, WIRELESS BASE STATION AND CELLULAR TELEPHONE |
摘要 |
Memory (237) stores relative correction values that indicate the differences of transfer characteristics between a) a radio unit made up of transmission circuit (211) and reception circuit (212), and b) a radio unit made up of transmission circuit (221) and reception circuit (222). Correction control unit (239), by means of phase shifter (240) and amplifier (241), uses the relative correction values to correct transmission signals. In similar fashion, the adaptive array apparatus and the radio base station perform corrections in order that identical array antenna patterns are formed at times of reception and transmission. <IMAGE> |
