  Abstract

This paper proposes a technology for performance enhancement of cyclic delay diversity OFDM system using frequency diversity. The frequency diversity in an OFDM system can be done as repetitive transmission of the same symbol on uncorrelated subcarrier, this makes modulation level larger according to the number of repetitive transmission for the comparison with the traditional transmission system. This technique, like cyclic delay diversity, has a benefit which it does not need any special subsidiary hardware irrespective of the increase of the number of transmitter. For the performance comparison, we simulate the proposed algorithm in multiple input single out channel environment, it shows a better performance enhancement in low dense modulation level in comparison with the traditional cyclic delay diversity OFDM system.
