Abstract: One embodiment is directed to a repeater system configured for use with a base station that implements a wireless interface that makes use of control transmissions that are retransmittable (for example, LTE PRACH transmissions). The repeater system implements a simplified mute or squelch function that transitions the repeater circuitry from a muted state to an unmuted state in response to a received power level crossing a first threshold value in connection with a first control transmission. Although that first control transmission will be lost, the repeater circuitry is configured to remain in the unmuted state in order to handle a retransmitted control transmission and to handle any associated subsequent control and user transmissions. The repeater system can be implemented as a single-node repeater and/or a distributed antenna system. Other embodiments are disclosed.

Abstract: A telecommunications system may include a measurement receiver to confirm the presence of a MIMO signal prior to decoding signals to avoid decoding spectrum that does not include MIMO signals. The measurement receiver may determine a fast Fourier transform (FFT) spectrum for asynchronous wideband digital signals received from two or more ports. The measurement receiver may determine an average FFT spectrum based on the determined FFT spectrum and identify a bandwidth of signals present in the average FFT spectrum. The measurement receiver may identify the MIMO signals present in the bandwidth of signals and decode only the identified MIMO signals.
