Abstract: Systems and methods for detecting unused channels in a cognitive radio system are described. In one method, data is communicated on a particular channel for a secondary receiver. In addition, a set of channels is iteratively scanned by collecting samples for each channel and for each iteration of the scanning. Here, iterations of the scanning progressively removes channels from the set of channels based on the collected samples and updates states of the channels in the set based on the collected samples to obtain a set of candidate channels. In response to detecting a pre-determined condition, communications on the particular channel are precluded and at least one of the candidate channels is evaluated by collecting additional samples on each of the channels. Further, at least one of the candidate channels is selected based on the evaluation for utilization by the one or more secondary receivers for data communication.

Abstract: Spectrum sensing methods and systems for detecting spectrum holes for use in cognitive radio secondary transmissions are disclosed. In one method, an indication of an assignment of a set of subcarriers to a primary user is received. The method further includes determining multitaper spectral estimates for at least a subset of the set of subcarriers based on the assignment of the set of subcarriers to the primary user by processing samples for the at least a subset of the set of subcarriers. In addition, a test statistic that is based on the multitaper spectral estimates is compared to a threshold to determine whether the set of subcarriers is utilized for primary transmissions to the primary user. Moreover, data signals are received on at least one of the subcarriers in the set of subcarriers if the set of subcarriers is not utilized for primary transmissions to the primary user.

Abstract: In accordance with aspects of the present principles, the quality of voice traffic and bandwidth utilization for data communication over a wireless multi-hop network may be improved. In an implementation of the present principles, a data packet transmission rate over a wireless multi-hop network may be controlled at an interface between the multi-hop network and a wired network based on a voice packet quality measure calculated from network parameters. Voice and data traffic quality and efficiency may be further improved by reordering a packet transmission queue at the interface to avoid timeout and/or varying a packet queue length at the interface using an acknowledgement window transmitted to a data packet sender.

Abstract: An improved aggregation scheme for wireless multi-hop mesh networks is disclosed. An aggregator at each node operates to merge VoIP packets at an ingress/source node with a forced delay, but at an intermediate node aggregated packets are either sent directly to their destination or to the next hop without deaggregation. A novel compression mechanism for compressing and decompressing the aggregated packets is also disclosed.
