基于NC-OFDM的未授权频段LTE-U非连续信道绑定方法研究
Research on a non-contiguous channel bonding method for LTE-U in unlicensed spectrum based on NC-OFDM
摘要
Abstract
The non-contiguous channel bonding under coexistence of LTE-U and WiFi in unlicensed spectrum based on non-contiguous orthogonal frequency division multiplexing ( NC-OFDM ) is proposed , thus a LTE-U can identify idle spectra by spectrum sensing to improve the spectrum efficiency with more flexible channel bonding .The simu-lation results demonstrate that the power spectrum density ( PSD ) of the LTE-U non-contiguous channel bonding based on NC-OFDM can meet the out-of-band leakage requirement of IEEE 802.11a.Furthermore, the NC-OFDM achieves a lower error rate compared with the contiguous orthogonal frequency division multiplexing ( C-OFDM) at the same signal-to-noise ratio, and the peak-to-average power ratio ( PAPR) at the transmitter is lower as well .关键词
