EFFICIENT IMPLEMENTATION OF CHANNEL CODING AND INTERSPERSING IN MIMO-OFDM SYSTEMS

The standards for high speed data communications in wireless LAN and MAN such as Worldwide Interoperability for Microwave Access (Wi MAX) is mainly used by Orthogonal Frequency Division Multiplexing (OFDM). An analysis of the different channel coding and interleaving schemes is presented in this paper which is used in MIMO-OFDM systems. Based on the bit error rate (BER) performance and hardware implementation issues a comparison of these schemes is presented. An examination is done on the effects of four different types of channel coding and interleaving schemes which are being used. The Wi MAX or IEEE 802.16 is used as a reference for imitation, execution, and analysis. The cross-antenna coding and per-antenna interleaving systems perform better under all signals to noise ratio (SNR) conditions for all modulation schemes which is shown from the above coding and interleaving schemes which are studied. The data rates for IEEE 802.16 are doubled for 2x2 MIMO systems without using the transmit diversity using the proposed schemes

MIMO TECHNOLOGY FOR WIRELESS COMMUNICATION AND WIRELESS COMPUTER NETWORKING

The demand of wireless communication in the field of Wireless Computer networking and mobile phones(communications) is constantly growing and need the tether less connectivity. The major limitations to this growth is the disadvantages of traditional wireless communication System due to the limitations of available frequency resources, Bandwidth, channel capacity, complexity, reliability, transmission data rate and physical areas. This paper addresses the overview of new technology Multi-Input-Multi-Output (MIMO) for wireless Communication and Wireless Computer networking system will be much more efficient to meet the heavy demand of Wireless communication in available limited frequency resources. MIMO channel is frequency selective (multipath) and is known to boost channel capacity for high-data rate transmissions, low power implementation, sophisticated signal processing algorithm. The FPGA based coding techniques will reduce the size, complexity and increase the reliability of connectivity
