UWB Pulse Design Method Based on Chebyshev Function Approximation

摘要：

Ultra Wideband radios will unavoidably face/cause severe interference from/to the existing narrowband systems nearby. To avoid interference, one of effective methods is to design appropriate pulse waveform. In this paper the problem of pulse design was equal to the problem of chebyshev function approximation and Remez algorithm was used to acquire the optimum pulse waveform. Matlab simulation results showed that the power spectrum density of the pulse based on chebyshev function approximation meets the power constraint of the objective spectral mask. The comparison were presented for the bit error rate performance analyses of the pulse position modulation time hopping ultra wideband impulse radio communication system employing the pulse and the second derivative Gaussian pulse in the additive white Gaussian noise channel. The performance of the pulse is better than the second derivative Gaussian pulse.
