International Classification:
H04L 27/00
US Classification:
375295, 375299
Abstract:
A Multiple Input Multiple Output (MIMO) single carrier wireless communication system is provided. The system includes a coder for performing block coding on symbols, an extender for collecting the block-coded symbols during one transmit (Tx) signal duration and for performing repetitive extension on the collected symbol vectors by an interval required in a frequency domain, an inserter for inserting ‘0’ to the repetitively extended symbol vectors so that the vectors are mutually orthogonal in a time domain, and a combiner for multiplying the ‘0’-inserted symbol vectors by a phase component so that the vectors are mutually orthogonal in the frequency domain and thereafter for combining the symbol vectors to generate a Tx signal for each antenna.

International Classification:
H04B 1/24
US Classification:
375241
Abstract:
A single carrier transmission scheme which utilizes space-frequency block coding and frequency domain equalization (SF-SCFDE) is proposed for frequency selective and fast fading channel. It is shown that employing this technique in slow fading environment depicts the same performance as that obtained with space-time coding scheme. However, in the more difficult fast fading channels, the proposed scheme exhibits much better performance.
