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.

摘要： A CMA-based antenna system is disclosed which shows an improved receiving performance by reducing phase differences in the received signals which have been weighted. The CMA-based antenna system comprises a plurality of antenna, weight circuits, an adder, an error detector and a synthesis controller. The synthesis controller controls the weight circuits so as not only to make the adder output at a preset level but also to cause any differences among the weight circuit outputs not to increase. In order to cope with an error of symbol synchronization and a delayed wave, the CMA-based antenna system may further have a kind of equalizer inserted before the weight circuit in each antenna circuit.

摘要： An adaptive transmission diversity apparatus utilizes a spread spectrum system, detects radiation patterns of direct and indirect waves, which have arrived in a time-shifted manner, by reception radiation pattern controllers. A transmission radiation pattern controller is utilized in accordance with a transmission radiation pattern. The transmission radiation pattern is determined by selecting a pattern from reception radiation patterns obtained by the reception radiation pattern controllers. This can ensure a higher transmission performance.

摘要： Received signal provided via plural antennas 101 are memorized in memory 102. First weight controller 103 calculates the first weights by which the received signals are weighted, and second weight controller 104 calculates the second weights using the received signals. Multipliers 107 and 108 multiply the memorized received signals by the first weights, while multiply the memorized received signals by the second weights when a channel quality of radio signals deteriorates due to a change of the radio signal's direction of arrival Adder 109 synthesizes the multiplication results. Propagation path distortion compensator 110 estimates a deterioration of the channel quality using synthesis result to compensate. Detector 111 detects the compensation result that is used as a parameter to calculate the first and second weights, which allows the apparatus to receive radio signals without deteriorating reception qualities when the channel quality deteriorates rapidly due to the change of the radio signal's direction of arrival.
