| Abstract(in English) | In this paper, we propose three new radio transmission schemes based on cyclic extended-and-shifted PN sequences in order to transmit broadband data with high frequency utilization efficiency under high mobility environment. The three new radio transmission schemes combine multicode transmission based on cyclic extended-and-shifted PN sequences with (1) Quadrature Amplitude Modulation (QAM) scheme for first modulation before code-spreading, (2) Multicarrier transmission, and conditioal Parallel Combinatory Spread Spectrum (PC / SS) technique, respectively. In order to evaluate transmission performance of the proposed transmission schemes, we calculated bit error rate (BER) performances under Additive White Gaussian Noise (AWGN), 1-path Rayleigh fading and equally distributed 2-path Rayleigh fading environments by using computer simulation. |
