Abstract
In this review paper, a study has been conducted on Unique Word Prefix. This paper shows a new transmit signal structure for OFDM.To avoid the interference between to signal we always require a guard band interval using cyclic prefix. But instead of that here a new term is used which is nothing but Unique Word Length where deterministic signal is used. Since Unique Words represent known sequences, they can advantageously be used for synchronization and channel estimation purpose. Furthermore it also generates the complex reed-Solomon (RS) code structure within the structure of sub-carriers which act as a unique word length code. To further improve the bit error ratio behaviour of the system, winner smoother was used to succeeding a zero forcing stage at the receiver. These beneficial properties are achieved while additionally featuring around the same bandwidth efficiency as conventional CP-OFDM.
