Alamouti based on spatial modulation for data transmission

Alamouti based on Spatial modulation for data transmission proposed an idea to have module that will transmit information bit with a high data rate, less power consummation and in a limited frequency spectrum. So to achieve this trellis coded spatial modulation (TC-SM) technique will be use. This technique is used for reducing power requirement in limited frequency spectrum with multipath propagation and interference is overcome. Spatial modulation (SM) maps a block of information bits into a symbol and unique antenna number. Symbols are formed by constellation diagram and antenna number is for receiving symbol at receiver module. Multiple Input Multiple Output (MIMO) antenna system is employed for high data rate and transmission is wireless.
