Future mobile communication systems aim to provide extremely high speed data transmission, especially in the downlink. Broadband orthogonal frequency code division multiple access (OFCDMA) with two-dimensional (2D) time and frequency domain spreading is becoming a very promising technique for high speed wireless communications due to its advantages over multi-carrier code division multiple access...
In this paper, we examine an enhancement of pulsed Multiband Orthogonal Frequency Division Multiplexing (pulsed MB-OFDM) systems for Synthetic Aperture Radar (SAR) Ultra-Wide Band (UWB) applications. The pulsed MB-OFDM system offers an efficient option for fulfilling the UWB high bandwidth channel requirements. This system combines the two major implementations of UWB, namely the impulse radio and...
