The demand for spectral efficiency in wireless communication is ever increasing. MIMO systems are very attractive for boosting the capacity of a wireless communication link in a rich multipath environment. It has been established that using antenna arrays at transmitter and receiver, the capacity is increased. The capacity is proportional to minimum of number of transmitting elements and receiving elements that is (min(NT, NR)). The capacity of MIMO system in the real-time scattering environment is reviewed. Basic antenna configuration in this environment reduces the channel capacity and this could be improved by proper design of antenna elements

Speech Enhancement emerges from the increased usage of digital speech processing applications like speech recognition, digital hearing aids and human-machine communication systems in our day to day life style. The development to make these applications mobile increases the variety of potential sources for quality deprivation. Speech enhancement methods are used to increase the quality of these speech processing devices and make them stronger under noisy conditions.
