Simulation And Analysis Of The DVB Transmission On The SystemView Software

This thesis mainly discusses the key technology and line transmission system of the popular digital TV in the world now, research DVB technical specification and performance characteristic of system. These communicate to SystemView system artificial function of software do brief introduction. On this base, utilize SystemView to simulate the transmission system which consist of compile code system, modulation and demodulation system and so on. carry on analyzing the result, have evaluated performance of each system.This thesis pays emphasis on analyzing the system structure and system flow, the core techniques, the channel characteristic and parameters of DVB system. In order to well know the realization of system flow and the capability of system, then with the software-SystemView, and using the relevant icon function in SystemView's DVB library, the thesis simulated the whole DVB system. The simulation carries through on three aspects as the ideal system, the disturbed systems with multipath distortion and gauss white noise distortion.At the end of simulation, it use examining means of communication system as BER (bit error rate) analysis and eye diagrams analysis, then gives a summarize and a comment to the system.
