- Abstract
- This letter proposes a unique-word-based single-carrier (UW-SC) system with frequency-domain decision feedback equalization (FD-DFE) for space-time block coded (STBC) transmissions. The STBC scheme can not be directly applicable to the UW-SC system, because its transmit sequence is reversed in the time-domain. To cope with this problem, we first design a new transmit sequence to fulfill the theorem of circular convolution, and propose a new corresponding receiver structure to have the transmit diversity. Unlike the cyclic prefixed SC system with FD-DFE, the proposed UW-SC system with FD-DFE greatly reduces an error propagation, thus yielding an improved performance as the number of feedback taps increases.
