Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for pre-correction of transmission in wireless communications.
SOLUTION: A wireless communication system includes a base station 102 having a plurality of antennas 104 for transmission, and transmits pilot signals to a subscriber station 120. The subscriber station 120 performs channel measurements on the signals received from the base station 102 through at least two transmission paths 106, 108, and sends path characteristic information for each path to the base station 102. By using the path characteristic information, the base station 102 determines the best transmission method of data in transmission of data from the multiple transmit antennas 104 to a single receive antenna 112 at the subscriber station 120. Through the use of pre-correction techniques, data signals are transmitted through the multiple transmission antennas so that signals received through the multiple transmission paths can be demodulated and decoded as a single signal.

Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques involve transmitting a signal through a first antenna, receiving feedback related to the signal transmission through the first antenna, selecting between the first antenna and a second antenna as a function of the feedback, and transmitting the signal through the selected antenna. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Abstract: Un procedimiento de comunicaciones en un sistema que comprende estaciones base (104) y estaciones de abonado (108), que comprende: transmitir una señal a través de una primera antena (114A) de una estación de abonado; recibir una respuesta relacionada con la transmisión de señal desde una estación base (104), en el que la respuesta es una señal de control de potencia; seleccionar entre la primera antena (114A) y una segunda antena (114B) de la estación de abonado en función de la señal de control de potencia, en la que la primera o segunda antena se conmuta si la señal de control de potencia comprende una solicitud para aumentar la potencia de transmisión; transmitir la señal a través de la antena seleccionada; y supervisar si se solicita una disminución posterior de potencia.

Abstract: A receiver chain ( 53 ) for use in a wireless communication system includes a compact, highly correlated, multi-element antenna. The multiple antenna elements ( 34 ) and ( 35 ) are configured to receive a signal from at least one base station. The highly correlated signals output from the antenna elements ( 34 and 35 ) are optimally combined in a controller ( 55 ) using a set of weighting factors. The set of weighting factors for each base station signal is determined in response to the spatial signatures of the received signals.
