Abstract :
For future 4G wireless system, higher spectrum efficiency and access speed are required, hence overlapping the time slot and multi frequency carriers will meet such demand, which forms the original thought of OVTFDM system. Based on Gabor transformation and under wavelet frame work, computation complex can be reduced on both transfer and receiver side. Further more, in OVTFDM system avoid cancellation of LSI, only detect user code sequence, classify it to recover original signal. In this paper we present a fast decoding algorithm by using Gabor neural network, and evaluate its performance.
