BPSK modulation based exact BER computation for network intra-chip RF interconnect

The rapidly increase of integration density, operating frequency, thermal stress and other complexities are pushing the conventional metal interconnects based IC technology to its material and physical limits. Radical alternative like on-chip radio frequency (RF) and wireless communication is being explored to replace the hard-wired metal interconnect. Currently for inter-chip and intra-chip RF/wireless communication, various single-input-single-output (SISO) schemes like BPSK, OQPSK, MSK and GMSK are being investigated. Therefore, this paper investigates the bit error rate (BER) by utilizing a Gaussian and Rayleigh multipath fading channel environment for the SISO system for network intra-chip RF interconnect.
