Title
Frequency-Hopped Space-Time Coded OFDM over Time-Varying Multipath Channel
Abstract
In this paper, we proposed a frequency-hopped space-time coded orthogonal frequency-division multiplexing (FHST-OFDM) over time-varying multipath channels. Although OFDM is robust against frequency-selective fading channels, it is more vulnerable to the time-varying channels and has a higher peak-to-average power ratio (PAPR) than single-carrier systems. In space-time block coded OFDM (ST-OFDM), channel time variations cause not only the intertransmit-antenna interference (ITAI), but also the inter-carrier interference (ICI). In this paper, based on the analysis of the ITAI and ICI in ST-OFDM systems, the FHST-OFDM transmission scheme is proposed to reduce both ITAI, ICI, and PAPR simultaneously. By combining the Alamouti scheme and the frequency hopping, full data rate and frequency diversity can be achieved by the proposed FHST-OFDM over the time-varying multipath channels. Finally, simulation shows that the proposed FHST-OFDM scheme gets better performance over time varying channels.
