| Abstract(in English) | We have proposed low power density baseband radio with frequency-domain differential spreading code for realizing underlay-type SU communications. Following the ABR signal-generation method based on the OFDM principle, we have proposed a system of spectrum spreading low power density baseband radio that offers frequency diversity gain in frequency-selective fading environments. When a strong PU signal existed in the same frequency band, however, there was a serious interference problem where SU system affected significantly from the PU system. Therefore, previously, we proposed an adaptive low power density communication scheme which uses white space so as not to overlap PU system in the same frequency band. In this paper, we investigate the condition where the differentially-encoded spreading code exhibits promising effects in suppressing the fading by changing the parameter of delay spread and spreading frequency band. Furthermore, we propose a multi-user transmission scheme where each user link has different delay spread. |
