The Design of Wireless Receiving Terminal with GMSK Demodulation

We describe the functions of the wireless receiving terminal with GMSK demodulation. In the hardware part, radioactive frequency circuits were designed to receive and filter the wireless signals. The demodulation module consisted of a MX589 chirp. The design of digital circuits was based on the singlechip GMS97L52. Software implemented the IC card authentication and the serial data process. The terminal receives data at high speed and functions with steady performance.
