Frequency decimation method to support dynamic control channels for wireless networks
Several operations in a wireless network, such as neighbour discovery and spectrum access coordination require a reliable control channel. However, for specific services, such cognitive radios and professional mobile radios, this channel has to be allocated on a dynamic basis, increasing the overhead and time involved in its setup. With this work, we propose a novel scheme for detection and communication between nodes. Through a frequency decimation algorithm performed in the analog domain, each user is capable of scanning a large number of channels simultaneously to detect its neighbours, without the need to increase its ADC speed and resolution.
