DS-OOK for Terahertz Band Nanonetworks

This study proposes a method for modulation and multiple access based on Direct Sequence On-Off Keying (DS-OOK) for the pulse-based communication in the Terahertz (THz) band. Using the unique properties of OOK as a modulation scheme, direct sequence could be employed as a mechanism to distinguish between distinct users transmitting simultaneously. Moreover, this scheme does not require coordination between transmitter and receiver and can be implemented in both ad hoc and infrastructure-based networks. The performance of the scheme is analyzed in terms of bit error rate for different spreading codes. Simulation results show that the choice of a proper spreading code plays a critical role in employing DS-OOK for THz band communication and could enhance the multiple-access performance even with a large number of interfering users.
