Abstract
In this paper, performance in term of BER of the OFDM-based TDCS is investigated in realistic CR contexts. According to the analyses and simulation results, it is observed that the OFDM-based TDCS operates better in random spectrum availability contexts than in continuous spectrum availability ones. Geometrical explanations are provided to give some insights to this phenomenon. Based on the explications, a new interleaved OFDM-based TDCS is proposed. Computer simulation results verify that the new proposal outperforms the OFDM-based TDCS without an interleaver, especially in the scenario where the percentage of available spectrum is rather low
