Design, Modelling and Performance Evaluation of Compressive Sensing Integrated DTCWT OFDM for mm-Wave Wireless Network-On-Chip

Scaling technology and shrinking transistor size have enabled the integration of multicore modules on a single chip for high-performance computing. Wireless Network-On-Chips has been demonstrated to be a viable choice for on-chip communication compared with wired communication, considering latency, energy, and data rate as performance metrics. Limitations in on–off keying modulation schemes have been addressed using OFDM modulation methods. In this paper, a new method based on the compressed sensing integrated dual tree complex wavelet transform (CS-DTCWT) is presented for OFDM modulation and demodulation operating in the mm-wave band. The CS-DTCWT-based OFDM model is developed in MATLAB and evaluated for its performance in the mm-wave operating frequency band of 20–60 GHz and for subcarriers of 128–1024. The BER performances of CS-DTCWT-based OFDM are demonstrated to be an improvement of 80% compared to FFT-based OFDM techniques. In addition, it can save 3.11% more energy than existing works. The proposed OFDM model is suitable for wireless NOC applications.
