Claim:
A high-speed sampling and low-precision quantification pulse ultra-wideband wireless communication method, comprising the following steps: generating a baseband pulse sequence at a sending end with digital method using a frame as the physical layer data transmission basic unit; modulating the baseband pulse sequence using sending data, and performing amplification and bandpass filtering; sending the signals which are controlled within the frequency band of 4.2-4.8 GHz after filtering into the air via an antenna; filtering and amplifying received signals at a receiving end, then directly performing high-speed sampling and low-precision quantification to convert the signals to digital domains, and designing synchronization, channel estimation and related detection methods suitable for high-speed sampling, low-precision quantification signals to process the signals converted to the digital domains and recover sent information, wherein the sending end consists of a channel encoder ( 1 ), a framer ( 2 ), a digital pulse generation and modulation device ( 3 ), a sending end amplifier ( 4 ), a sending end bandpass filter ( 5 ) and a sending antenna ( 6 ) which are sequentially connected; and the receiving end consists of a receiving antenna ( 7 ), a receiving end bandpass filter ( 8 ), a low-noise amplifier ( 9 ), an analog to digital converter ( 10 ), a digital detector ( 11 ) and a channel decoder ( 12 ) which are sequentially connected, characterized in that the frame as the physical layer data transmission basic unit consists of a prefix character, a synchronous pattern, a frame header part and a data part, wherein the pulse interval of the pulse sequences sent by the prefix character part is T 1 , and the pulse interval of the pulse sequences sent by the other parts is T 2 ; the value of T 1 is larger than the length of an energy main body part of wireless channel impulse response, and the value of T 2 is smaller than that of T 1 to ensure sufficiently high pulse repetition frequency and obtain high data transmission speed; the prefix character consists of two parts of pulse sequences, the first part S 11 ={+, −, +, −, . . . , +}, wherein + and − indicate a positive pulse and a negative pulse respectively, and the pulse number thereof is an odd number; the second part S 12 ={−, +, −, . . . , +}; and the synchronous pattern is a selected pseudo random positive-negative pulse sequence.
