A Novel Underlay TV Spectrum Sharing Scheme Based On Polarization Adaption for TD-LTE System

Free registration required

Executive Summary

Spectrum opportunities in time, space and power domain are exploited by secondary users in traditional Cognitive Radio studies. While spectrum opportunities in polarization domain, namely simultaneous utilization of spectrum between primary and secondary system with polarization signal characteristics, is exploited inadequately. With the merits of polarization mismatch, primary system lies in the orthogonal polarized domain of secondary system, and interference to primary system can be mitigated. This paper studies the cognitive underlay TV spectrum sharing with the merits of polarization mismatch for TD-LTE system. In this direction, a novel Polarized Underlay Spectrum Sharing (PUSS) scheme is proposed for the coexistence of TD-LTE and DTV system.
