Spatial modulation technology demonstrates significant advancements over traditional methods like V-BLAST and MRC. This spatial modulation program achieves 4bit/s/Hz spectral efficiency using BPSK, 4QAM, and 8QAM modulation schemes, with implementation details on antenna selection algorithms and signal mapping techniques.
When achieving 3 bits per symbol (i.e., 3 bit/s/Hz spectral efficiency) in Spatial Modulation (SM) systems, we compare two configurations: 4 transmit antennas with BPSK modulation versus 2 transmit antennas with 4-QAM modulation. This analysis includes implementation considerations such as antenna indexing, constellation mapping, and spectral efficiency calculations.
