Abstract- In this paper, ordered successive interference cancellation (OSIC) is adopted with minimum mean square error (MMSE) detection to enhance the multiple-input multiple-output (MIMO) system performance. The optimum detection technique increases the system complexity with improved error rate performance. Therefore, MMSE-OSIC detection is used which gives reduced error rate compared to traditional MMSE with a considerable level of complexity. The system performance is analyzed in a composite

Chapter 1 Multicarrier techniques This section deals with the importance of multicarrier techniques. 1.1 Multi carrier techniques In a single carrier system, single fade causes the whole data stream and undergo distortion i.e frequency selective fading. The Single carrier systems also suffer with heavy Inter Symbol Interference . In telecommunication Inter Symbol Interference was a form of distortion of signal in which one symbol interferes with the subsequent symbol

wireless internet and technologies which are capable of providing higher capacities and link reliabilities. Multiple-input-multiple-output (MIMO) is based on communication system which is able to fulfil these objectives. MIMO is an expansion of smart antennas systems. There were traditional smart antennas which occupy multiple antennas at receiver, whereas In MIMO system multiple antennas are engaged at both sides at transmitter as well as receiver side. The multiple antennas at the transmitter and

range without the requirement of any additional bandwidth. This led to the development of MIMO Systems. In Multiple-Input Multiple-Output (MIMO) technology, multiple antennas are used at both the transmitter and receiver to improve the functioning of the wireless communication system. We accomplish this objective by exploiting the spatial domain of the transmission medium. In this chapter, we describe the MIMO system model along with a brief discussion of its

Gamal (1979), this case create a virtual MIMO, nodes can collaborate and share, to form a virtual antenna distribution MIMO antenna system is the simplest alternative and more promising for the application. This is done through communication is called cooperation. (Cover and El Gamal, 1979) According to Cover and El Gamal (1979), a good performance in wireless communications Multiple-Input Multiple-Output (MIMO) has drawn attention. The benefits of MIMO communication has been widely recognized

and comparatively in expansive way of achieving a transmit diversity gain in system such as GSM. The principle goal of MIMO technology is to improve either the quality (BER) or the data rate of the communication by means of adequate signal processing techniques at both ends of the system. The capacity can increase linearly with the number of antennas when using MIMO system. MIMO can obtain both multiplexing gain and diversity gain thus significantly increasing the system capacity as well as improving

Multiple-input multiple-output (MIMO) [2, 3, 30, 31] systems were introduced in order to enhance the performance of the wireless communications systems to provide robustness, high data rates, and reliability by overcoming the channel fading with the use of multiple antennas. A MIMO system offers redundancy through the multiple independent channels, which are created between the transmitting and the receiving
