Performance Analysis of OFDM Based UWB Systems Enhanced with Frequency-Domain Spreading
— In this paper, a performance analysis of orthogonal frequency-division multiplexing (OFDM) based ultra-wideband (UWB) systems with frequency-domain spreading is presented. A co...

Frequency-Domain Oversampling for Zero-Padded OFDM in Underwater Acoustic Communications
Although time-domain oversampling of the received baseband signal is common for single-carrier transmissions, the counterpart of frequency-domain oversampling is rarely used for mu...

Performance analysis on an MAP fine timing algorithm in UWB multiband OFDM
In this paper we develop a fine synchronization algorithm for multiband OFDM transmission in the presence of frequency selective channels. This algorithm is based on maximum a post...
