Abstract: PROBLEM TO BE SOLVED: To provide near maximum data transfer speed and to process multipath phasing over all the ranges by using coding and antenna diversity, together with phasing predictive feedback and suitable control processing. SOLUTION: The speed and transmission power of data at (m) pieces of respective independent channels are regulated by linear processing which are supplied by a base station and processors 111 and 131 in mobile units 101 and 103, and under the limitation of constant power, total data transmission speed is made maximum. Feedbacks x(k) and u(k) concerning channel characteristics from respective reception matrixes 130 and 150 are utilized for this adjustment. In order to provide independence or low correlations between the phasings of respective reception antennas, orthogonal polarization antennas 1201 ...120m and 1521

Abstract: PROBLEM TO BE SOLVED: To improve the performance of a receiver by composing a device of a processing circuit for supplying a processed signal and a delay circuit coupled to the processing circuit and performing prescribed delay so that the processed signal can be coincident with following data burst. SOLUTION: A signal u(t) transmitted from a mobile station 10 through a mobile antenna 12 is received through M pieces of antenna 18 to a base station 16 respectively as received signals from s1 (t) to sn(t). The received signals are respectively weighted by using a magnifier 20 having weight from w1 (t) to wn(t), and respectively correspondent weight signals from x1 (t) to xn(t) are generated. The weight from w1 (t) to wn(t) are generated from a weight generating circuit 22 while using the signals from s1 (t) to sn(t) and an output signal y(t). In order to improve signal quality at the time of outputting, the signals from s1 (t) to sn(t) are weighted and coupled at an applique processor circuit 14. Weight control is performed for suppressing the average square law error of the output signal to a minimum.

Abstract: An apparatus for performance improvement of a burst mode digital wireless receiver comprises a processing circuit for processing a plurality of received signals and providing a processed signal and a delay circuit for introducing a predetermined delay to the processed signal. The delay circuit is coupled to the processing circuit. The predetermined delay is such that the processed signal is delayed to correspond with a later data burst. The processing circuit weights and combines the received signals, where the processing circuit reduces a mean squared error of an output signal. The processing circuit weights and combines the received signals using a predetermined symbol pattern within a sync sequence within a time slot.

Abstract: A communication system and method, particularly adapted for use in adaptive antenna arrays, are presented. A plurality of signals containing a desired signal, interference, and noise are received through an array of antennas connected to a base receiving station. The signal arriving at each antenna i s weighted according to computations which adjust those weights as a function of received interference and noise power in an unequal manner, based on the estimation accuracy of the interference and noise, which in turn depends on factors such as interference to noise power ratios and fading rate.

Abstract: An adaptive high speed data transmission system is described. In one aspect, the transmitter for this system employs a plurality of transmit antennas which have controllable offsets. The tranmsitter also includes signal coding circuitry suitable for use to address transmission impairments due to fast fading in the transmission channel. At the receiver, the received signal is analyzed to determine the fading characteristics of the channel. Where slow fading is detected, the offsets are employed to convert the slow fading into fast fading. The channel characteristics are continually resampled and these characteristics are used to adjust the transmitter and the receiver to achieve optimal transmission speed.
