STUDY PAPER ON WIRELESS MIMO-OFDM SYSTEM USING MODULATION WITH COMMUNICATION CHANNEL

Abstract

Today, communication has become an integral part of our lives and the past 10 years witnessed various innovations in the mobile telephony. The demand for data services also increased. The main need of any communication system is basically high speeds of data transmission with higher accuracy and reliability. Multiple input multiple output (MIMO) provides high-rate transmission through expended channels by multiple array antennas on both sender and receiver side. Also orthogonal frequency division multiplexing (OFDM) is well-known as the most appropriate technique for high data rate transmission. In this paper, we propose a multi-user multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system with adaptive modulation and coding to improve system capacity with maintaining good error performance.
