Abstract
Multiple Input Multiple Output (MIMO) has become one of the most exciting field in modern engineering.It has become one of the key technologiesfor wideband wireless communication systems .It is mainly used to increase capacity and data rate of any wireless systems .In this paper,we exploit the space and time diversity to decode the quasi and rotated quasi space time block codes (QOSTBC) based on dent channel model.For doppler shifting and rayleigh distribution we make use of dent channel model. A general Quasi and rotated quasi Space -Time Block Coded (STBC) MIMO structure is presented in this paper. BER analysis is presented in terms of code rate and diversity achieved using Quasi and Rotated quasi STBC methods. Furthermore, simulations are carr ied out using above two OSTBC methods with various modulation schemes in quasi staticdent channel model and then optimum coding method is suggested for 4×2 quasi and rotated quasi Space time block coded MIMO systems .This provide fast decoding and gives better performance of communication system. BER analysis is presented in terms of diversity and code rate.
