Performance analysis of a mimo multi-carrier code division multiple access wireless communication system with smart antenna

Abstract

Multicarrier CDMA wireless communication systems are very much attractive due to its insensitivity to frequency selective fading, diversity in frequency and high spectral efficiency. Numerous research works are reported on performance of MC-CDMA wireless link over faded channel with numerical simulations. In this thesis, analytical approach is developed to evaluate the bit error rate performance of a MC-CDMA system with multiple input and multiple output (MIMO) configuration along with smart antennas. Analysis are carried out to find the expression for BER with Zero-Forcing detector. Results are evaluated numerically for different system parameters. Simulations are carried out without and with smart antenna to validate the analytical results. Results show that there is significant improvement in receiver sensitivity due to cancellation of interference by smart antenna.
