Objective: In the wireless communication the Inter Symbol Interference (ISI) is a major barrier caused by multipath fading which has a strong negative impact on Bit Error Rate (BER) and affects the high speed data transmission over the wireless channel. Methods: The equalization and channel estimation techniques are available at the receiver (Rx) to reduce the ISI when the channel is affected by multipath propagation effect. Further to decrease the influence of ISI or to improve the quality of the channel condition from the transmitter (Tx), it is reliable to use Relay with Beam-Form (BF) technique because ISI is related to a channel’s spatial property. It is natural to expect BF techniques which are often deployed in Multiple Input Multiple Output (MIMO) systems that help to enhance the performance of the system. Findings: In this model, the half duplex Relaying is provided with MIMO antennas with the Amplify and Forward (AF) Relaying protocol. To reduce the ISI and error rate, this study proposes Improved Transmit Beam-Form (ITBF) with equalizationandRelay to be employed with MIMO Multi-Carrier Code Division Multiple Access (MC-CDMA) system. Application: Simulation result depicts the proposed system with ITBF and Relaying is highly reliable to achieve high speed data transmission.
