Time diversity approach for intra-chip RF/wireless interconnect systems

Increasing operating frequency of current and future VLSI systems is putting physical constraint on hard-wired metal interconnect. RF/wireless interconnect is considered to be one of the alternatives to conventional metal interconnect. This paper evaluates the bit-error-rate (BER) performance of to coherent binary phase-shift keying (BPSK) with linear and systematic channel coding in an intra-chip RF/wireless interconnect system. The results indicate that for a certain range of received signal- to-noise (SNR) ratio, channel coding improves the performance of the RF/wireless interconnect system. It is also shown analytically that performance can be improved at low SNR with the application of time-diversity approach by using interleaver and deinterterleaver.
