MODELLING AND ANALYSIS OF A CDMA2000 PHYSICAL LAYER USING AWGN TO EMULATE A WIRELESS CHANNEL

This work deals on simulation and evaluation of the performance of physical layer of wireless communication system of CDMA - 2000 requirement using radio configuration - 3 under forward fundamental channel 1x in terms of bit error rate (BER) by using MATLAB 7.9.0 (2009b) . Built - in functions in MATLAB 7.9.0(2009 b) version was used to achieve this. A signal simulator was employed accord ing to the physical layer requirement of the IMT - 2000 CDMA system. The data wa s transmitted in a frame by frame basis through a time - varying channel. The transmitted signal was degraded by AWGN at the front end of the receiver.
