Abstract: Data service transmission interruption is minimized by initially setting up a cluster of channels to transmit data services. As the need arises to switch channels due to the detection of an incumbent signal, the data services can be switched with substantially no delay. A group of channels from those available in a wireless network are chosen to form a cluster of channels. Each channel within the cluster is set up to convey data services with channel parameters being stored. A first operating channel is chosen from among the cluster of channels to transmit the data services. While the data services are being transmitted on the first operating channel, out-of-band spectrum sensing occurs on the other channels. Upon predetermined criteria a channel switch occurs. As each channel has already been set up the necessary channel parameters are retrieved from storage and restored without data service interruption.

Abstract: Described herein are various principles for operating a transmitter circuit to reduce noise affecting a signal being generated and reducing jitter. In some embodiments, a circuit is operated in a way that switching occurs at or above a bit rate of transmission, such that at least one switch changes state at least for every bit. Operating the circuit in such a way leads to a switching rate that is above a resonant frequency of the circuit and prevents large oscillations and noise from being inserted into the signal and causing communication problems.
