The invention discloses a pulse UWB communication system based on CS theory, the signal detection theory is introduced into CS by sparse in digital signal processing algorithm, combined with the increase of the transmitter module, with pre encoding random pulse generating effective observation module, UWB channel and low speed sampling device to realize the digital signal to the transmitter X send the. Then, the reconstructed digital signal X can be reconstructed and restored by the commonly used restoration and reconstruction algorithm in CS theory. The communication system of the present invention, receiver does not need a program like parallel programs need to parallel correlators and low speed sampler, which overcomes parallel hardware implementation complexity problems; at the same time the receiver directly using a low speed sampler for sampling, do not need to use the analog to information converter, can be avoided effect of causal low-pass filter, analog to information converter in the observation of the observation, overcome the sparse matrix problem caused by causality in the serial program.
