—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, multi-user 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 of such a code is also introduced and included in the comparison. Results show that there are trade-offs among the various metrics used and, even if there is no clear winner method, the novel method has good results in almost all metrics.
