Abstract
An encoder in a transmitter uses space-time trellis coding. An input bitstream is multiplexed to produce in parallel a set of output bitstreams. A multiplier applies a code generating weight to each output bitstream, which are combined, mapped and transmitted by a single antenna.
Claims7
An apparatus for encoding an input bitstream in a transmitter using space-time trellis coding (STTC), comprising:
- encoding the input bitstream to produce in parallel a set of output symbols;
- a multiplier to multiply each output symbols with complex number;
- an adder to sum up all multiplied values to form a linear combination of the output symbols.
