Hybrid bit-to-symbol mapping for spatial modulation
Hybrid bit-to-symbol mapping for spatial modulation
In spatial modulation (SM), the information bit stream is divided into two different sets: the transmit antenna index-bits (TA-bits) as well as the amplitude and phase modulationbits (APM-bits). However, the conventional bitto- symbol mapping (BTS-MAP) scheme maps the APM-bits and the TA-bits independently. For exploiting their joint benefits, we propose a new BTSMAP rule based on the traditional two-dimensional (2-D) Gray mapping rule, which increases the Hamming distance (HD) between the symbol-pairs detected from the same transmit antenna (TA) and simultaneously reduces the average HD between the symbol-pairs gleaned from different TAs. Based on the analysis of the distribution of minimum Euclidean distance (MED) of SM constellations, we propose a criterion for the construction of a meritorious BTS-MAP for a specific SM setup, without the need for any additional feedback-link or extra computational complexity. Finally, Monte Carlo simulations are conducted for confirming the accuracy of our analysis.

Abstract
In spatial modulation (SM), the information bit stream is divided into two different sets: the transmit antenna index-bits (TA-bits) as well as the amplitude and phase modulationbits (APM-bits). However, the conventional bitto- symbol mapping (BTS-MAP) scheme maps the APM-bits and the TA-bits independently. For exploiting their joint benefits, we propose a new BTSMAP rule based on the traditional two-dimensional (2-D) Gray mapping rule, which increases the Hamming distance (HD) between the symbol-pairs detected from the same transmit antenna (TA) and simultaneously reduces the average HD between the symbol-pairs gleaned from different TAs. Based on the analysis of the distribution of minimum Euclidean distance (MED) of SM constellations, we propose a criterion for the construction of a meritorious BTS-MAP for a specific SM setup, without the need for any additional feedback-link or extra computational complexity. Finally, Monte Carlo simulations are conducted for confirming the accuracy of our analysis.
