Bit-Error-Rate Performance of Inter-Chip RF/Wireless Interconnect Systems

With the ever increasing degrees of integration, and operating speed in ultra large-scale integrated (ULSI) circuits conventional approaches of hard-wired metal interconnects are encountering fundamental limits. Several revolutionary approaches have been proposed for an alternative to metal interconnect. One of the most feasible approaches is RE/wireless interconnects. This paper evaluates the system bit-error-rate (BER) performance in an inter-chip RE/wireless interconnect system. The results indicate that for a certain range of received signal-to-noise (SNR) ratio, error control coding (ECC) 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.
