Abstract: A method of monitoring an element in wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first device, but within a bandwidth of a second, subsequent device. The operational noise measurement is alternatively obtained by tuning an input band of the element to shift the input band partially or completely outside of a bandwidth of a first device to create an open band or by suppressing an input of the antenna and measuring noise within the open bandwidth of the element of the wireless communication network. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the element may be received at a signal receiver and compared to a reference. The reference is a function of components of the wireless communication system in a leakage path of the leakage signal.

Abstract: A repeater and associated method of use includes at least one antenna element for communicating in one direction and at least one antenna element for communicating in another direction. A radio frequency uplink path and a radio frequency downlink path are coupled between the antennas. At least one of the radio frequency uplink path or the radio frequency downlink path includes an adaptive cancellation circuit.

Abstract: A distributed antenna system having improved data transmission features incorporates endpoints of the system, which are coupled together by serial data link. At the endpoints, processing may occur utilizing processing circuitry to determine similarities between multiple signal streams.

Alternatively, all signals might be sent, but may be compressed with compression circuitry before the signals are transmitted over the serial link. At the endpoint of the system, the signals are reconstructed for further processing and transmission.

The processor determines an optimal modification scheme for the I or Q component that minimizes an output power of the undesirable signal component. An output value of the function is minimized by having the optimal modification scheme as an input.
