English Abstract

In this thesis, the performance of space time coded (STBC) spatial modulation system – system is investigated with the use of code division multiple access (CDMA) using a simulation on MATLAB program of bit error rate (BER).

The system under study uses 4 antenna at both side – transmitter and receiver- to deploy a multipath system, where the channels in each receiver is considered to be un-correlated channel, which mean any change in each channel doesn't affect the other channels.

The system is designed starting with MPSK/MQAM modulator followed by spatial modulation encoder then STBC encoder.

Finally CDMA encoder with pseudo random code is used and full synchronized between transmitter and receiver.

At the receiver side the opposite is made by starting with CDMA decoder followed by STBC decoder then spatial modulation decoder and finally the MPSK/MQAM decoder, taking into consideration that the error was evaluated using maximum likelihood detection method (ML).

The BER is simulated on MATLAB program and investigated for different modulation schemes and number of parameters such as M-array size and spreading code length.

The investigation is carried out assuming Alamouti’s scheme and uncorrelated Rayleigh fading channels, the results show that the performance of the system is very promising.
