Embodiment Construction
[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:
[0031] The basic block diagram of the system of the present invention is figure 1 , the system can realize one-to-one and many-to-one spread spectrum wireless data transmission macroscopically. User data is transmitted wirelessly after direct sequence spread spectrum and BPSK (Binary Phase Shift Keying, Binary Phase Shift Keying) modulation at the sending end, and then recovered after down-converting, synchronous despreading and synchronous demodulation at the receiving end Raw data. When the system is one-to-one data transmission, a 31-bit spreading code can be used, and the system transmission speed is 80kbps; when the system is many-to-one transmission, a 127-bit spreading code is used, and the system transmission speed is 20kbps .
[0032] Figure 2a Shown is the hardware module diagram of the sending end of the present invention, the software pr...
