    摘要: A non-frequency translating repeater (110, 210, 300) for use in a time division duplex (TDD) radio protocol communications system includes detection retransmission and automatic gain control. Detection is performed by detectors (309, 310) and a processor (313). Detection can be overridden by processor (313) using logic elements (314). Antennae (220, 230) having various form factors can be used to couple a base station (222) to a subscriber terminal (232) which can be located in a sub-optimal location such as deep inside a building or the like.

    摘要: A repeater environment is provided operative to deploy a feedback cancellation loop that is adaptively coupled with an antenna array such that a selected metric can be derived by deploying a selected filter bank having an automatic gain control operative to process the signal on a bin by bin basis and the derived metric can be applied to the antenna array and feedback cancellation loop combination to improve signal integrity and amplification. In an illustrative implementation, an exemplary repeater environment comprises, a transmitter, a receiver, an equalized feedback cancellation loop circuitry comprising a filter bank, the cancellation loop being operatively coupled to an antenna array. In the illustrative implementation, the feedback cancellation loop can receive signals as input from a cooperating antenna array and provide output signals such as a feedback leakage signal to a cooperating antenna array.

    摘要: An antenna apparatus which can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective signal control component such as a switch. The switch position of each antenna element is programmed for optimum reception during, for example, an idle mode which receives a pilot signal. The antenna array creates a beamformer for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. Various techniques for determining the proper arrangement of signal control components for each antenna element are accommodated.

    摘要: A wireless repeater employing echo cancellation uses a non-linear element in digital baseband to compress the digital transmit signal waveform, thereby allowing distortions in the transmitter circuit as well as interference to be cancelled. In one embodiment, the repeater applies non-linear baseband compression to the digital transmit signal in the digital domain to reduce the peak-to-average amplitude of the digital transmit signal prior to digital-to-analog conversion and prior to over-the-air transmission and prior to sampling of the digital transmit signal for use as the reference signal for echo cancellation. The intentionally introduced non-linear distortion in the transmit signal improves echo cancellation and stability of the repeater. In one embodiment, the non-linear compression is applied only when the digital transmit signal is at or exceed a given power level or a given gain level.
