Detection and Performance of the OFDM-Based Transform Domain Communication System
In this paper, based on orthogonal frequency division multiplexing (OFDM) technology, we proposed a new modified implementation of transform domain communication system (TDCS), which is wtih great potential to be applied in the cognitive radio (CR) environment. Compared with the traditional TDCS, the complex RAKE receiver is avoided in our proposal. The performances of this OFDM-based TDCS are investigated through theoretical analyses and simulation in Additive White Gaussian Noise (AWGN), flat Rayleigh and multipath Rayleigh fading channels, respectively. The results show that this OFDM-based TDCS can be a promising transmission scheme in CR contexts, such as IEEE 802.22.
