Abstract
Unique word - orthogonal frequency division multiplexing (UW-OFDM) is a novel transmit signal structure for OFDM where the usual cyclic prefixes (CPs) are replaced by deterministic sequences, the so-called UWs. Since unique words represent known sequences, they can advantageously be used for synchronization and estimation tasks, but also for improving the bit error ratio (BER) behavior of an UW-OFDM system. Recent research results have demonstrated the superior BER behavior of UW-OFDM over conventional CP-OFDM used for real-world communication systems, e.g. for the IEEE 802.11a WLAN standard. In this paper we extend these investigations by considering different and data rate equivalent UW-OFDM and CP-OFDM configuration setups. We show simulation results for various frequency selective environments and additionally compare UW-OFDM with UW based single carrier/frequency domain equalization (UW-SC/FDE) systems.
