Title: Code receiver
Inventor: TANAKA KIYOSHI
IPC: H04L25/06
Filed: 1992-08-24
Abstract: PURPOSE:To obtain a code receiver having a highly sensitive preamble detecting function with a simple circuit by sending an analog base band signal through a low pass filter(LPF) and detecting that an output from the LPF is less than a prescribed threshold for a prescribed time. CONSTITUTION:When a radio wave obtained by the frequency modulation of a preamble is inputted to an antenna 31, an analog base band signal appearing as the output of a receiver 32 becomes an alternate waveform with a half of the frequency of the code transmission speed of the preamble signal. The -6dB interruption frequency of the LPF 52 is set up to be less than a half of the frequency. Thereby a frequency signal whose peak voltage is compressed is obtained. Since the frequency signal passes through a full-wave rectifying circuit 53, its negative component is folded to the positive side. When the output of the circuit 53 is compared with a prescribed threshold, the voltage value of the preamble signal can be always set up to a low state. When the low state continues for several cycles, the sense of the preamble can be judged, so that high sensitivity can be attained by a simple circuit.
