Performance Analysis of MIMO-OFDM for Wi-Max Using Graphics Processing Unit(GPU)
Orthogonal Frequency-Division Multiplexing (OFDM) has become a popular modulation scheme for wireless protocols because of its spectral efficiency and robustness against multipath interference. Although the components of various OFDM protocols are functionally similar, they remain distinct because of the characteristics of the environment. Recently, Graphics Processing Units (GPUs) have been used to accelerate the signal processing of the PHYsical layer (PHY) because of their great computational power, high development efficiency and flexibility. In this paper, the authors describe the implementation of parameterized baseband modules using GPUs for two different OFDM protocols, namely, 802.11a and 802.16.
