Improvement of Performance of MIMO System Using Different Protocols

Communication system performance can be improved by applying MIMO (Multiple Input Multiple Output) technique, however alternatively we can apply cooperative diversity technique where in each terminal (known as source, destination and relay) there is only single antenna. Now by combing those terminals in different combination in TDMA (Time Division Multiple Access) different protocols can be designed, those protocols can be used as MIMO (Multiple Input Multiple Output), SIMO (Single Input Multiple Output) and MISO (Multiple Input Single Output). Those three protocols can be analyzed by applying sinusoidal, coding and exponential increasing input also improve the performance of those protocols by repeating their operation in consecutive time interval (For two time slots the transmitted signal (Square wave) is retrieved at the receiver by considering that receiver have knowledge about CSI (Channel State Information).
