The 7th step, payment end unit and gathering end unit all obtain the indication of having concluded the business from network-side Database Unit by internet.
Phase-shift keying (PSK) PSK modulator approach:
Phase-shift keying (PSK) PSK modulator approach is a kind of modulation technique that represents input signal information by carrier phase, every two bit of described Frame, key data frame, successful control frame or the failed control frame crossed through RS algorithm coding are divided into a code element, be mapped as I road signal through this code element through planisphere and Q road signal two paths of signals carries out respectively high frequency modulated, signal modulated carrier used in I road is cos ω t, that Q uses on road is the carrier wave sin ω t that phase differential 90 is spent, wherein, ω=2 π f
0, f
0for a selected high frequency frequency in 16kHz～18kHz, not adjust the phase place of carrier wave as the phase place of benchmark, Phase Stacking corresponding to different symbol is to forming with tonal signal in carrier wave separately.If the quantity of distinct symbols that modulation forms is M, be labeled as MPSK(M and be 2 n power, n>=2), the contained quantity of information of this each symbol is log
2mbit, therefore, only need be according to the demand of practical application, increase or reduce the value of M in when modulation, just can realize the object that improves or reduce transfer rate, and choose all at high band, therefore frequency interference free performance is better, is conducive to decoding end and is correctly decoded.
Because the one end of carrying out sound wave payment adopts mobile terminal handheld device, in sound wave communication process, can be due to of short duration variations such as handheld device angle, positions, cause the sound signal that receiving end is received in signal intensity, to produce brief fluctuations variation, react in the modulated signal amplitude of receiving.So depend on the amplitude modulation technique of modulated signal amplitude (as QAM, ASK etc.) for information, can produce certain probable bit error.On the contrary, information depends on the phase modulation technique PSK of carrier phase, and interference free performance and stability are better.
Control mark:
The length of controlling mark is 1 byte, and beginning flag is byte 0x0F, and end mark is byte 0xF0, and accurate indication is 0x34, and error flag is 0xAB.
Audio data frame and control frame form:
Referring to Fig. 4, is the structural representation of Frame.4 byte check byte in Frame are passed through RS(15,11) algorithm (Read-Solomon error correcting code) draws, be that every 11 byte valid data can generate 4 check byte, can correct the error of transmission of 2 bytes, the filling 0 of Frame valid data less than 11 bytes.Referring to Fig. 5, is the structural representation of control frame, is three byte lengths.
