【Abstract】 This paper introduces the implementation of the high performance wireless data transmitter. The transmitter works in the wireless voice channel (25 kHz bandwidth), and the transmission data rate is 9 600/19 200 bit/s. The transmitter utilizes GMSK modulation technology, and the error detection and error correction are applied. By software programming, the transmitter can flexibly support different kinds of communication protocols.更多还原
