Abstract
This paper proposes a partial spectrum transmission (PST) method for dynamic spectrum access (DSA). For DSA, it is preferable to select modulation scheme which is appropriate for the low-priority user's condition and radio environment by taking into account the required Eb/N0, frequency efficiency and PARR. When received SINR condition is better, QAM is selected for high-speed packet communication. However, QAM may cause link performance degradation due to the shorter Euclidean distance. On the other hand, PSK is capable of preventing such performance degradation. In this paper, we propose a PST method using PSK. It is shown by computer simulations that the required Eb/N0 at a BLER of 10-2 and the PAPR for the proposed PST (1/2) are approximately maximum 1dB better than those of 16QAM respectively.
