<p>PROBLEM TO BE SOLVED: To reduce the complicatedness of the constitution of a mobile receiver and to synchronize the timing of a code phase precisely in detail by applying a complex constitution part which belongs to a normal receiver to only the pilot signal generator of a transmitter. SOLUTION: This device has a means 2 which generates jitters of the timing of a pilot signal code with balance with the timing of a signal code, means 6, 8, and 10 which measure the energy of the pilot signal while the pilot signal is advanced and delayed, and means 16 and 18 which generate directing signals based upon the difference in measured energy. To obtain the response of a peak, the timing of the code phase is controlled with an operation signal. Namely, a radio connecting method is used for code division multiplex access making use of direct sequence spread spectrum.</p> |
