  • Publication number: 20250211470
    Abstract: Systems and methods for pulse shaping of baseband signals in a communication network using Electro Quasistatic signal is disclosed. The system up-samples baseband symbols in digital domain for generating an up-sampled baseband symbols. Further, the system pulse shapes the up sampled baseband symbols in the digital domain to generate pulse shaped symbols to be transmitted as a bandlimited waveform based on spectral mask requirements. The system up-converts a frequency of the pulse shaped symbols in digital domain to a desired frequency band for generating a frequency up converted pulse shaped waveform based on a sampling frequency and a symbol rate. The system further generates a reference analog signal (St) by converting the frequency up converted pulse shaped waveform in digital domain to analog domain.

  • Publication number: 20250211355
    Abstract: The present disclosure provides a synchronized time division multiple access (TDMA) network is disclosed. The synchronized TDMA network includes computing devices and a central control system. The central control system monitors transmission of data packets between the computing devices and the central control system. The central control system assigns a communication slot to each of the computing devices, for synchronizing the central control system with the computing devices. The central control system determines a communication schedule for each of the computing devices. The communication schedule defines a direction, computing devices involved, and types of data transactions occurring at a predetermined time frame. The central control system transmits a data packet to each of the computing devices at predefined intervals for aligning a timing parameter of communication of each of the computing devices and the central control system.
