Generalized Block-Based Spatial Modulation and Space Shift Keying

摘要

Spatial modulation (SM) uses the spatial dimensions (antenna indices) to transmit information along with the conventional modulation symbols. The SM scheme fixes the number of active antennas in a transmit vector. The block-based spatial modulation (BSM) varies the number of active antennas in each transmit vector, but keeps the total number of active antennas over a block fixed. This work generalizes the BSM scheme by better utilization of spatial dimension to achieve a higher data rate and lower bit error rate (BER). We also extend the proposed generalized block-based scheme to space shift keying to improve its data rate and BER performance.
