Title: CDMA synchronization method by using separated channel
Inventor: RYU SEUNG MUN
IPC: H04B7/216
Filed: 2001-01-10
Abstract: PURPOSE: A method for synchronizing a CDMA signal using a separated synchronizing channel is provided to simplify a receiving circuit by superceding complicated initial synchronizing process and synchronization tracing process by a bit synchronization process of a general digital transmitting signal, thereby easily using a CDMA method. CONSTITUTION: An RF receiver for a CDMA signal(21) receives and demodulates a CDMA modulation signal and an RF receiver for a synchronizing signal(22) receives demodulates a synchronizing signal for making a baseband signal respectively. Phase change due to frequency difference between a transmitter and a receiver, is compensated by multiplying the baseband signal of the CDMA modulation signal by the baseband signal of the synchronizing signal. At the same time, the polarity of the CDMA modulation signal changed by a synchronizing code is adjusted. A code pattern is extracted from the baseband signal of the synchronizing signal by using a DPLL(Digital Phase Lock Loop)(23) and a clock is restored. A synchronizing time is detected with a pattern comparator(24) by using the extracted code pattern. The received CDMA baseband signal is multiplied by the orthogonal codes equal to the orthogonal codes used in the transmitter by using the synchronizing time and then correlation is obtained by using an integrator(24) for restoring data transmitted from the transmitter.

Title: Speed control method for srm
Inventor: JUNG YUN CHEOL
IPC: H02P25/08
Filed: 2001-02-08
Abstract: PURPOSE: A speed control method of a SRM is provided to control broad range RPM through a lead angle and duty control of a pulse width modulation signal. CONSTITUTION: A speed of a SRM is controlled by determining whether the rotation speed of the motor exceeds 1500 RPM by a microcomputer. If the rotation speed of the motor is less than 1500 RPM, a lead angle is changed to a duty of a desired RPM while fixing the duty of a pulse width modulation signal. The pulse width modulation signal is applied to gates of NMOS transistors so as to control the on/off period of the NMOS transistors to rotate the motor. When the motor drives at a low speed, RPM is reduced proportionally to a delay time. If the speed of the motor exceeds 1500 RPM, the duty of the current pulse width modulation signal is changed to the duty of the desired RPM to be applied to the gates of the NMOS transistors while fixing the lead angle.
