Abstract
The paper represents regular method of synthesis of a bit signal for the wireless communication networks using frequency manipulation for coding of the transferred information. The synthesized signal has two-level envelope and low sidelobe level in the set area of a spectrum. The synthesis method is based on repeated operations of a delay and addition of initial sequence of pulses with rectangular envelope. As a result of synthesis the signal with pulse-width modulation is obtained. Software implementation of the algorithm was created using development environment NI LabVIEW. Temporal and spectral properties of the signal are researched. The signal can also find application in Doppler's ultrasonic systems that use high-powered nonlinear amplifiers.
