Low-Weight Code Comparison for Electromagnetic Wireless Nanocommunication

Electromagnetic communication among nanosensors using time-spread on-off keying (TS-OOK) modulation in terahertz band promises very high transmission rates (up to several terabits per second). Due to scarce battery capacity in nanosensors, energy efficiency is a very important aspect in nanocommunication, as are also bandwidth expansion, multiuser interference, and robustness against transmission errors. This paper compares various low-weight codes found in the literature using metrics specific to nanocommunication. A small variation in such a code is also introduced and included in the comparison. Results show that there are tradeoffs among the various metrics used and, even if there is no clear winner method, the novel method has good results in almost all metrics.
