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 for processing a plurality of spatially modulated streams each received through a plurality of antennas at a receiver, comprising:
- applying Maximum Likelihood (ML) Log Likelihood Ratio (LLR) based detection to the spatially modulated streams to detect antenna selection (AS) bits;
- applying multiple input multiple output (MIMO) detection to separate the spatially modulated streams into respective streams for decoding, wherein the MIMO detection is based on the detected AS bits;
- and
- decoding the respective streams.
A processing system comprising a memory and a processing device coupled to the memory, the processing device being configured to:
- apply Maximum Likelihood (ML) Log Likelihood Ratio (LLR) based detection to a plurality of spatially modulated streams received at a plurality of receiver antennas to detect antenna selection (AS) bits;
- apply multiple input multiple output (MIMO) detection to separate the spatially modulated streams into respective streams for decoding, wherein the MIMO detection MIMO detection is based on the detected AS bits;
- and
- decode the respective streams.
A computer readable medium having instructions stored thereon, wherein the instructions, when executed by a processing device of a processing system, cause the processing device to:
