    • The design of Digital UART by using VHDL 

      Norhuzaimin, Julai; Lio Siang Peng, John; Kismet, Hong Ping (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
      UART is acronym for Universal Asynchronous Receiver Transmitter and is used for data communication between two devices. The UART translates between parallel bits and serial bits of data. This means that only one bit can ...

    • Field testing of prototype DQPSK modem on the Skudai - Baling and Skudai - Chemor HF Radio link 

      Ahmad Sazali, Senawi; Ahmad Zuri, Sha’ameri (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
      The unpredictability in HF propagation results in multipath fading phenomena affect reliability in data communication. Random phase due to fading causes phase synchronization error at the receiver. This problem can be ...

    • FPGA implementation of MCPFSK modulation for HF data communication 

      Fitri Dewi, Jaswar; Ahmad Zuri, Sha’ameri (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
      Digital modulation based on FSK is widely used in HF data communication. This is due to simplicity in implementation by noncoherent detection and robustness due noise and phase synchronization error. Hardware based design ...
