    摘要: A method of controlling gains within a repeater may include determining a power control set point value which controls a transmit power of a mobile station (MS), and receiving a downlink signal from a base station transceiver system (BTS). The method may further include measuring a power of the received downlink signal, and computing a power level of a signal expected at the uplink of the repeater, wherein the computing is based on the measured downlink power and the power control set point value. Finally, the method may further include adjusting a gain of at least one amplifier based on the computed power level. An apparatus for controlling gains in a repeater may include a baseband processor for performing the above method.

    摘要: A method in a wireless repeater selects one or more carriers out of all carriers for amplification and transmission. The non-selected carriers may be blocked to mitigate delay spread, uplink noise contribution or other effects on the repeater environment due to multiple repeaters. The carriers may be selected based on signal characteristics, signal usage, and/or other parameters.

    摘要: Methods and apparatus for estimating a loop delay value (Ndelay) in an interference cancellation repeater are presented. For example, a method may include setting a repeater gain to an initial gain value, setting a delay parameter to an initial time value, and measuring a loop gain associated with the delay parameter and the repeater gain by detecting a feedback signal with an echo canceller disabled. The method may further include determining whether the measured loop gain is larger than a previously measured loop gain, and if so, designating the delay parameter as the loop delay value (Ndelay); and decrementing the delay parameter when the measured loop gain is not larger than the previously measured loop gain, and when the delay parameter is not at a final time value. The method may iterate until the delay parameter is less than or equal to the final time value.

    摘要: A wireless repeater has a receiving antenna for receiving an input signal and a transmitting antenna for transmitting an amplified signal where the input signal is a sum of a remote signal and a feedback signal. The repeater includes an echo canceller receiving the input signal and generating an echo cancelled signal by estimating a feedback channel between the transmitting antenna and the receiving antenna and cancelling a feedback signal estimate from the input signal, an amplifier for amplifying the echo cancelled signal and providing the amplified signal to the transmitting antenna, and a variable delay element receiving the echo cancelled signal and introducing a first delay to the echo cancelled signal. The first delay is selected to optimize the estimation of the feedback channel, thereby optimizing the cancellation of the feedback signal. The delayed echo cancelled signal is coupled to the echo canceller as a reference signal for estimating the feedback channel.

    摘要: A method for controlling gain in a wireless repeater includes computing a gain control metric indicative of a loop gain of the repeater and detecting changes in a signal power of a gain control input signal where the gain control input signal is taken from any point in the feedback loop of the repeater. When a large power swing in the gain control input signal is detected, the method operates to discard at least a portion of each gain control metric measurement for a first duration before continuing with computing the gain control metric. In another embodiment, the method may include discarding samples of the gain control input signal used in computing the gain control metric for a first duration when a large power swing in the gain control input signal is detected.
