Collaborative Spectrum Sensing with Reporting Based on OFDM
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 3
Abstract
In this paper, we present a collaborative spectrum sensing that employs an orthogonal frequency division multiplexing (OFDM) to report the binary local spectrum sensing decisions to a cognitive base station (CBS) where the final decision about the presence or absence of the licensed user (LU) is made. During OFDM transmission the channel between the CR users and the CBS is assumed to be quasi-static multipath fading. The impact of reporting signal to noise ratio on the probability of errors for transmission between CR and CBS is presented in this paper. The effect of symbol time offset (STO) between CR user and the CBS on the reporting performance and on the overall false alarm and miss detection probabilities at the CBS is also investigated in this paper. Analytical and selected simulation results for system performance are presented in this article.
