摘要： A wireless repeater includes an echo canceller to cancel an estimated feedback amount from an input signal and a delay to delay the input signal. The delay may be selected to decorrelate a remote signal from a signal to be transmitted by the repeater.

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： A method for providing repeater communication in a wireless repeater deployed in a multi-repeater environment includes inserting a message signal into the transmit signal of the repeater. The message signal may be a unique or quasi-unique low power spreading sequence uniquely identifying the repeater from other repeaters in the environment. The message signal may also contain information relating to the operational characteristics of the repeater. The message signal may be detected by another repeater or by an end-user wireless communication device.

摘要： A method for adjusting per-carrier gains in a repeater is presented. The method may include determining a separate gain value for each carrier frequency in a signal. The method may further include applying the separate gain value to each carrier frequency in the signal to form a per-carrier gain adjusted signal. The method may also include adjusting the separate gain values based upon a per-carrier stability metric.

摘要： A method for estimating a feedback channel for a wireless repeater uses frequency domain channel estimation on samples of a pilot signal and samples of a receive signal. The pilot signal samples may be delayed to align the largest channel tap to a given reference time. A time domain feedback channel is generated by retaining both the causal taps and the non-causal taps of the channel estimate.

摘要： A wireless repeater includes an echo canceller to cancel an estimated feedback amount from an input signal and a reference receiver to sample a portion of the transmit signal prior to over-the-air transmission for use as the reference signal for channel estimation. More accurate channel estimation is obtained by using the reference signal from the reference receiver as the reference signal accounts for distortions in the transmitter circuit of the repeater.
