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.
Claims20
A method for single carrier space-frequency (SF-SCFDE) transmission over frequency selective and fast fading channel, the method comprising:
- receiving communication block streams;
- encoding the received communication block streams to produce communication blocks;
- adding a cyclic prefix to each communication block to form transmission blocks;
- and
- communicating each transmission block through a frequency selective fading channel.
An apparatus for single carrier space-frequency (SF-SCFDE) transmission over frequency selective and fast fading channel, the apparatus comprising:
- a space-frequency encoder that receives and encodes communication block streams;
- a cyclic prefix adder that adds a cyclic prefix to each communication block;
- and
- antennas that communicate each communication block.
A system for single carrier space-frequency (SF-SCFDE) transmission over frequency selective and fast fading channel, the system comprising:
- a transmitter having a space-frequency encoder that receives and encodes communication block streams, a cyclic prefix adder that adds a cyclic prefix to each communication block, and antennas that communicate each communication block;
- and
- a receiver having antennas that receive communication blocks from the transmitter, a structure to remove the cyclic prefix, and a decoder.
