Abstract

Modified digital prolate functions (DPF) are addressed in this paper, applied as waveforms for downlink MC-CDMA systems and providing higher transmission rates. Those waveforms, thanks to their double orthogonality and energy concentration in restricted interval properties, enable specific processing at the receiver. Design and analysis of advanced receivers exploiting the abovementioned DPF properties and computer simulations that demonstrate their performance improvement compared to MC-CDMA system with Hadamard codes are presented.
