Investigation of UTRA FDD Data and Control Channels in the Presence of Noise and Standard Defined Channel Models

In this paper, the main aim is to design and simulate UTRA FDD control channel in the presence of noiseand wireless channel by using FDD library/Matlab box set that can be used to design and implement somesystems. Moreover, a test and verification of the library is achieved with different channel models such asAdditive White Gaussian Noise (AWGN), fading and moving channel models. FDD library are employed todesign whole transmitter and receiver. Then we had tested AWGN channel and some other channel models.Also we illustrated what are control channels DCCH and the other one as understanding the whole system.Moreover, the standards have been covered as well as implemented the whole transmit and receive chainplus the generation of DPCH, DPCCH channel. we had tested the performance against the AWGN noise.Then we have studied different channel models that are defined in the standard, used the few of them likethe fading channel and moving channel. We have tried to compare the performance in terms of MonteCarlo simulation by producing the BER curves. We have also change some channel parameters like phase,number of multipaths and we have tried to see the performance of the model in the presence of actualchannel model.
