1. A first method of beam-indexed spatial modulation (BISM) for a multiple-input and multiple output (MIMO) module having a transmitter end and a receiver end, comprising:

  • step a) confirming that the MIMO module has a plurality of beams, the number of the plurality of beams is NB, each of the plurality of beams is an individual channel constituted by one of antennas at the transmitter end and one of antennas at the receiver end;

    step b) providing an index to the NB beams through a NT×

    NR channel matrix H, wherein NT are an integer number of a plurality of transmitting antennas and NR are an integer number of a plurality of receiving antennas, which H is decomposed by the singular value decomposition and represented by
