Abstract
This paper addresses relationships between diversity techniques and channel coding rates for OFDM and SC-FDE systems. In OFDM systems it is important to select proper channel coding rates according to multi-path channel profiles and low channel coding rates are required with cyclic delay diversity compared to the case of space time coding. On the other hand, it is not necessary to use low channel coding rates for SC-FDE systems where DFT spreading is applied to OFDM and relatively high channel coding rates can be used regardless of diversity techniques.
