Abstract: A system and method for providing low overhead floor control in a distributed control two-way radio communications network (200) including one or more subscriber stations (201,205, 213, 215, 217) and one or more peer stations (203, 207, 211) interconnected via an Internet connection (209) using no central control. A subscriber station (201) utilizes a floor request during a timed floor request window (FRW) for requesting floor control to a given peer station (203). The system and method provide for consistent floor control decisions throughout the communications network (200) which includes a policy to block additional floor requests from local subscriber stations once an initial floor request has been received. This enables each peer to receive an identical set of floor requests as every other peer within the FRW such that every peer will grant the floor to the same subscriber.

Abstract: Techniques for detecting and suppressing jammers are described. A receiver may perform post-FFT jammer detection and pre-FFT jammer suppression. The receiver may transform an input signal to obtain a frequency-domain signal and may detect for jammers in the input signal based on the frequency-domain signal. The receiver may determine powers of a plurality of carriers based on the frequency-domain signal and may detect for jammers based on peaks in the powers of these carriers. The receiver may filter the input signal (e.g., with a notch filter) to suppress the detected jammers. Alternatively or additionally, the receiver may perform post-FFT jammer detection and post-FFT jammer suppression. The receiver may determine whether jammer is present on each carrier based on data power and channel power for that carrier. The receiver may modify (e.g., zero out or reduce) the frequency-domain signal on carriers with detected jammers.
