Abstract
Methods and systems that can enable antenna selection (AS) and data bits in transmitted spatially modulated (SM) streams to be detected at a receiver using different detection methods. In example embodiments, encoding for an AS stream is done separately at a transmitter than encoding for data streams, enabling a receiver to use one type of detection for AS bits and a reduced complexity type of MIMO detection for the data bits.

A method performed at a transmitter, comprising:
- applying forward error correction (FEC) encoding to encode a first portion of an incoming data bitstream into a first encoded bitstream;
- applying FEC encoding to encode, independently of the first portion, a second portion of the incoming data bitstream into an antenna selection (AS) bitstream;
- encoding each of a plurality of spatial streams into respective symbols, each spatial stream being a different respective portion of the first encoded bitstream;
- and
- transmitting each respective one of the symbols over a respective transmit antenna set, each respective transmit antenna set including one or more antennas transmitting the respective one symbol, the respective transmit antenna set for transmitting each respective one symbol being determined by AS bits from the AS bitstream.
A processing system comprising memory and a processing device coupled to the memory, the processing device being configured to:
- apply forward error correction (FEC) encoding to encode a first portion of an incoming data bitstream into a first encoded bitstream;
- apply FEC encoding to encode, independently of the first portion, a second portion of the incoming data bitstream into an antenna selection (AS) bitstream;
- encode each of a plurality of spatial streams into respective symbols, each spatial stream being a different respective portion of the first encoded bitstream;
- and
- transmit each respective one of the symbols over a respective transmit antenna set, each respective transmit antenna set including one or more antennas transmitting the respective one symbol, the respective transmit antenna set for transmitting each respective one symbol being determined by AS bits from the AS bitstream.
