Abstract:the channel detector has a wide range of uses, because the time domain detector requires special hardware based on the existing, has a long development cycle, the shortage of time, in order to solve this problem, this paper proposes a binary sequence based on time-domain channel detector design. The system selects two kinds of binary sequences, that is, the maximum length sequence and the Golay complementary sequence, and theoretically analyzes the advantages of using the two binary sequences as the excitation signal in the time domain detector. The channel detector is proposed in this paper is the experimental platform connected by some experimental instruments and the construction of the platform, through the control of PC, finally the experimental results show that in the millimeter wave band (MMW) for the 57-64 GHz band, the system faster to detection and anti linear interference.
