BER Performance of Adaptive Spatial Modulation
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 2
Abstract
Adaptive spatial modulation(ASM) is a recently developed communication system that generalizes both Spatial Modulation(SM) and Transmit Antenna Selection(TAS). Data stream is divided in signal carried information and spatial carried information. Using Huffman coding transmitter can adjust activation probability of transmit antenna according to receiver side feedback. Huffman coding helps to assign binary data antenna index. Antenna information bits are mapped to corresponding transmit antenna according to constructed code. Activation probability is derived by optimizing capacity which helps to select transmit antenna. Bit error rate is calculated to compare performance of ASM and SM. ASM minimizes bit error and there by producing improvement in performance.
