Abstract Aimed at the real-time and reliability requirement of data transmission for the industry vehicle and rail transit train, a data transmission system by induction radio based on TMS320F28335 DSP was designed. This system includes 2DPSK modulation module which is composed of DSP+CPLD chips and power amplifier circuit, and also includes demodulation module which is composed of a DSP chip and signal preprocessing circuits, etc. The testing results indicated this system has some more stable performance, baud rate which can be selected and lower bit error rate, which is adapted to the modern industry data transmission demands and was suitable for bad industrial environment.
