    Abstract
  • In the high speed mobile communication systems, the channel is usually a random or jitter of uniform frequency channel because of the fluctuations in speed of moving vehicles and multi-path effect. This fact leads to a study of non-uniform spectrum system. A novel non-uniform multi-tone system based on Ramanujan sums was proposed. First it was proved that the transform pair based on Ramanujan sums can be perfectly reconstructed at some circumstance. Then an efficient realization structure to build a multi-tone system named as Ramanujan Fourier multi-tone system (RFMT) was proposed and simulated in additive white Gaussian noise (AWGN) and multi-path channels. With the help of non-uniform spectrum and diversity character, RFMT can protect different data in different sub-carriers and achieve a 4 dB lower Eb/N0 than orthogonal frequency division multiplexing (OFDM) in 3-path channel using zero-forcing equalization with bit error rate (BER) 10-5.
