Abstract :
In this paper, we proposed a novel MB-OFDM UWB system, which exploits projective geometry constructed LDPC code as its channel encoding code. We emphasized on the construction of projective geometry LDPC code and the model of the UWB communication system. Also we simulated this novel system with computer software and compared the performance with uncoded UWB system. Finally we make a conclusion that projective geometry constructed LDPC codes are strong competitors to FEC codes for error control in communication systems.
