Abstract:
In this thesis, a hardware is designed and implemented for testing the perfoemance of MIMO communication systems in LTE standard using SCM channel model. This hardware can be used for measuring the BER of 2x2 wireless systems. This hardware is the first channel emulator, with hardware implementation which is using SCM channel model and implementation of a similar one has not been reported.In addition to the implementation of the mentioned channel emulator, a new approach is used for implementing a Gaussian variate generator (GVG) which is implemented on both FPGA and ASIC and shows better characteristics in comparison with the works done in the past. ASIC implementation of this part is done in with the tail accuracy of and 32-bit output precision and the core can produce 532 Gaussian variates per second using 0.49mm2 of hardware area. The main contributions of this thesis are the hardware design and implementation of the SCM channel model for the first time and testing the dsign on FPGA and design and hardware implementation of a Gaussian variate generator with a new method which is tested on FPGA and implemented as an IC.
