Abstract
The single RF chain transmitter implementing space modulation provides wireless multiple-input multiple-output (MIMO) communications that are implemented through a single radio frequency (RF) chain using multiple transmit antennas. A symbol stream is used to provide a single RF signal output modulated by a quadrature or complex symbol stream. An RF switching circuit is used to direct the single RF signal output sequentially to antenna subsets including one or more antennas of a plurality of antennas. An index of the antenna subsets is provided to allow switching by the RF switching circuit according to the index of antenna subsets provides spatial modulation (SM) of the RF signal output as transmitted to through the antennas. The transmitted RF signal output is rendered as a single RF chain through the plurality of antennas as transmitted through the antenna subsets.
