Abstract :
In recent years, graphics processing unit (GPU) has escalated interest in computational applications. In this paper, we proposed an efficient implementation of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) worldwide interoperability for microwave access (WiMAX) communication system using GPU. The WiMAX system uses space time block code (STBC) and maximal ratio receive combining (MRRC), which is computationally rich due to complex multiplication and fast fourier transform (FFT) computation. To harness the benefits of GPU computing power the complex multiplications in MRRC and FFT are computed in parallel. The processing time for FFT and MRRC under CPU and GPU environment are analyzed and presented.
