Dynamic Spectrum Access with Tunable Bandwidth for Multi-standard Cognitive Radio Receivers

Abstract : This paper deals with the design of low complexity dynamic spectrum access (DSA) scheme for Cognitive Radios (CRs) to search the vacant band(s) of tunable bandwidth, Bh. The DSA scheme with tunable Bh is very critical for CRs considering the coexistence of multiple communication standards in wideband input signal with channel bandwidths ranging from 25 kHz to 20 MHz and users expectations of seamless integration of multiple services on single terminal. The proposed scheme is designed by integration of our allpass transformation and coefficient decimation method based variable digital filter and suitably modified Upper Confidence Bound based decision making algorithm. The simulation results and complexity comparisons show that the proposed DSA scheme offers superior performance in terms of total number of vacant band(s) selection (and hence high spectrum throughput) for wide range of Bh as well as spectrum occupancies and total gate count savings of 20-90% over existing schemes.
