摘要

The ionospheric scatter communication system is challenging due to its large transmission loss and usually works under low signal to noise ratio (SNR). A novel blind SNR estimation algorithm for single carrier interleaved frequency division multiplexing (SC-IFDM) system is proposed to improve the accuracy of the estimation. The received time domain data are used to estimate the signal power and no...
