Systems () and methods () for dynamically managing Secondary User Node ('SUN') access to a segment of a wireless spectrum licensed for use by Primary User Nodes ('PUNs'). The methods comprise: detecting physical data transfers by PUNs (-) at first licensed frequencies (f, f, f, f) during slot sample times of a first epoch (t1-t15); generating a report comprising sensed spectral data indicating (a) during which of the slot sample times each physical data transfer was detected by a respective SUN (-) and (b) at which of the first licensed frequencies each physical data transfer occurred; receiving a report broadcasted from a remote SUN at a non-licensed frequency during a respective slot report times (t16-t19) of the first epoch; and analyzing the sensed spectral data of the reports to determine a time for using a first licensed frequency without interfering with or only minimally interfering with use thereof by PUNs.

Cross-layer, cross-node cognitive network enhanced dynamic spectrum allocation

An electronic device includes a nonlinear power amplifier, a predistortion coefficient calculator, and a memory polynomial predistortion filter coupled to the nonlinear power amplifier and to the predistortion coefficient calculator. The memory polynomial predistortion filter may include a plurality of finite impulse response (FIR) filter stages, and a summer coupled to the plurality of FIR filter stages. The FIR filter stages may functionally operate in parallel or may include a series of FIR filters coupled in parallel.
