| Popis: | In this paper, the inherent advantage of On-Off Keying (OOK) Modulation for full duplex communication has been investigated in the physical layer in the context of short distance on chip communication such as wireless network on chip (WiNoC). Here, the OOK transmitter is designed in a manner such that it also works as an RF canceler. This novel design neither requires an external phase inverter nor an attenuator to achieve the cancellation of the self-interfered signal. The distance between the transmitter and the receiver being very small for WiNoC, the self interference cancellation requirement of the typical 100 dB of power reduces by more than 60%. The isolation achieved by the OOK transmitter cum RF canceler is 19 dB as simulated and shown in this work. This energy efficient OOK transmitter has been designed with BSIM-CMG (Common Multi-Gate) FinFET model at 60 GHz. The power dissipation of the transmitter is 23 mW. In tandem with the path loss in the propagation domain and antenna cross polarization this design meets the required isolation and opens up a great opportunity for using full duplex communication for WiNoCs with the energy efficient non-coherent OOK modulation. No work has investigated the feasibility of full duplex communication for WiNoCs or for any other on-chip communications in the physical layer in the past. |
