    摘要: The present invention relates to a method for adaptively controlling a transmission radiation pattern. Radio signals coming through a plurality of paths are received and demodulated for each path. The received level or received quality of each demodulated signal is compared to each other to select a signal with the highest level or most excellent quality. A path corresponding to a selected path is set at a path for transmission. When a plurality of signals each with an almost equal level or received quality exists in signals demodulated for each path, a history of transmission power control command (TPC) transmitted from a communication partner is referred. In other words, the reception condition in a communication partner is checked. Thereby, it is judged whether or not the currently selected path is appropriate as the path for transmission.

    摘要: A multiplication circuit 152 multiplies signals, which are subjected to variable directional transmission, by weighting factors with respect to the respective antennas 101 to 103, and outputs the resultant to combining circuits 155 to 157, respectively. The signals input to the combining circuit 155 are combined and radio modulated by a radio section 104, and transmitted from the antenna 101. Whereby, in a case where variable directional transmission is performed with respect to only some terminal apparatuses, signals, which are subjected to no variable directional transmission, can be transmitted after spreading them from the respective antennas of an array antenna.

    摘要: A frequency offset may be determined by detecting phase information for both a one-symbol difference and a two-symbol difference of a received known signal. Half a value representing the phase information detected for the two-symbol difference is averaged, for a particular interval, with a value representing the phase information detected for the one-symbol difference. The frequency offset is determined from the average.

    摘要: When carrying out directive reception using an adaptive array antenna apparatus, a plurality of diversity reception circuits which differ in communication environment follow-up performance are used for reception and the reception output with the best reception quality is selected. The environment follow-up performance of the other non-selected diversity reception circuits is dynamically changed, preferably every time a selection is made by a selector based on the environment follow-up performance of a selected diversity reception circuit.
