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 controlling gain in a wireless repeater implementing echo cancellation determines a signal-to-interference-noise-ratio (SINR) of the input and output signals of the repeater and adjusts the gain of the repeater to optimize an achievable data rate and a coverage area of the repeater. The repeater gain may be decreased to increase the data rate and increase the achievable SINR of the output signal while the coverage area is reduced. Alternately, the repeater gain may be increased to decrease the data rate and decrease the achievable SINR of the output signal while the coverage area is increased.

摘要： A method of controlling gains in an interference cancellation repeater includes receiving a combined signal which comprises a downlink signal transmitted from a base station transceiver system (BTS) and a feedback signal. The method further includes performing interference cancellation on the combined signal to substantially remove the feedback signal from the downlink signal. The method further includes determining a path loss between the BTS and the interference cancellation repeater based on the downlink signal after interference cancellation is performed, and adjusting at least one gain in the interference cancellation repeater based on the path loss. An interference cancellation repeater which controls gains based on a downlink path loss includes a first and second transceiver coupled to a first and second antenna, respectively, and a baseband processor configure to perform the above method.

摘要： A method for estimating a feedback channel for a wireless repeater using frequency domain channel estimation estimates an error correction term using a most recent channel estimate and cancels the error correction term from a current block of the receive signal. Then, the feedback channel is estimated using frequency domain channel estimation and using a current block of the pilot signal and the corrected block of the receive signal. A channel estimate error term may also be estimated and subtracted directly from the channel estimate.

摘要： A method for computing a gain control metric used in controlling gain in a wireless repeater operates to store correlation and normalization values associated with the gain control metric for the previous N samples in registers. For each new sample of the gain control input signal, the correlation and normalization values are computed by discarding the multiplication terms of the obsolete sample and adding the multiplication terms of the new sample to the stored correlation and normalization values. In this manner, the complexity of the computation is greatly reduced and the complexity of the computation does not increase with the integration length.

摘要： Apparatus and methods implementing transmission schemes that can flexibly achieve the desired spatial multiplexing order, spatial diversity order, and channel estimation overhead order are provided. For example, an apparatus is provided that includes a processor configured to allocate different subcarriers to different antennas at different times. A memory is coupled to the processor. The processor can be further configured to map a traffic channel to a specific sequence of the different subcarriers at the different times. The processor can also be further configured to transmit the traffic channel on only one of the different subcarriers at each time in the different times. The processor can be integrated with at least one of a base station and a terminal.
