An efficient spectrum sensing scheme for cognitive radio

Cheng, S. and Stankovic, V. and Stankovic, L. (2009) An efficient spectrum sensing scheme for cognitive radio. IEEE Signal Processing Letters, 16 (6). pp. 501-504. ISSN 1070-9908

Abstract

The paper combines distributed source coding and compressive sampling for efficient spectrum estimation. Two or more cognitive radios sample the spectrum compressively and independently compress their observations using multiterminal source coding. A central hub collects compressed streams from these radios before performing joint multiterminal source decoding followed by iterative signal reconstruction. Simulation results are provided for two radios performing practical multiterminal source coding with uniform scalar quantization and systematic turbo codes for Slepian-Wolf coding and error protection.
