Interest in terahertz (THz) technology is related to various applications such as object detection, spectroscopy, security, and telecommunications. However, one of the challenges of THz technology is the implementation of effective communication between the transmitter and the receiver. Modulation technique like orthogonal frequency division multiplexing (OFDM) is already used in the THz band. However, the most widely used transmission method, on-off keying (OOK) scheme, presents several problems in high-rate data detection. In fact, the purpose of this work is to design in Matlab Simulink a transmission chain based on the energy detector, frequently used for transmitting radio pulses, since applications focused on the ultra-wide band are much less complex to implement and consume little power. In this regard, we present a delay-modified energy detector that will allow the sample to optimally select the maximum energy levels corresponding to the sending of logical bit 1 and logic bit 0. And we have chosen an energy detector with OOK modulation in the additive white Gaussian noise (AWGN) channel. The proposed system has a low cost, high performance and low power consumption, so it can be effectively used for a THz system.
