BER performance comparison between CDMA and UWB for RF/wireless interconnect application

In ultra large-scale integrated (ULSI) circuits conventional approaches of hard-wired metal interconnects are encountering fundamental limits. In order to get beyond this problem different revolutionary interconnect approaches have been explored. One of the most feasible approaches is RF/wireless interconnects, which are based on low-loss and dispersion-free microwave signal transmissions, near-field capacitive coupling and modern multiple-access technologies like code division multiple access (CDMA), frequency domain multiple access (FDMA), time domain multiple access (TDMA), ultrawideband (UWB) etc. In this paper BER performance of multi-carrier CDMA (MC-CDMA) and UWB transceiver for RF/wireless interconnect system are compared. Besides, required electronic overhead for these two transceivers is also mentioned.
