| Abstract: |
| The noise performance in binary digital modulation system is analysed in the presence of gaussian hybrid additive white bimodal noise.The mathematical model of narrowband multi-model process is put forward for studying more general circumstance.At the same time a general algorithm for signal detection in hybrid noise environment is presented. It has some general significance and is the perfection and supplement of the theory of communication and signal processing based on Gaussian noise. On the basis of theoretical analysis,simulation results are given and analysed. |
