Abstract: PURPOSE: An apparatus and a method for canceling a group-wise parallel interference of a CDMA system with a multiple transmission speed are provided to cancel a group-wise parallel interference by determining ranks of signals using output values of a maximal ratio combiner received to each finger and power measured values of the fingers, and by grouping the fingers according to the ranks. CONSTITUTION: A received intermediate frequency signal(100) is generated through a receiver antenna, a carrier frequency demodulator and an analog to digital converter. The received signal(100) is converted into a baseband signal(107). After that, the baseband signal(107) is stored in a buffer(102). The signal(107) is inputted to an adder(106). A DCB(Despreading and Channel estimation Block) is composed of a timing circuit(108), a PN code generator(109), a demodulator(111) and a channel and power estimator(112). The synchronization acquisition circuit(108) performs a processing of PN code acquisition and tracking using the signal(107). The PN code generator(109) generates a PN code(110) using synchronization acquisition information outputted from the circuit(108).

Abstract: PURPOSE: A method of re-synchronization by transmission/reception sequence hopping in an asynchronous code system is provided to continue communication by recovering a communication fail due to the synchronization fail between a transmitting and a receiving port automatically after a random time when a code system is applied to a channel. CONSTITUTION: A transmission sequence makes a code sequence hop to a sequence state of integer times position from an initial state after transmitting a synchronous signal and encodes a signal by applying the determined code sequence after the position, and a reception sequence the code sequence hop to a sequence state of integer times position from the initial state after detecting the synchronous signal and decodes the signal by generating the original sequence from the position.

Abstract: The method involves several stages and sub systems. In the first stage, theperiodic time of the fundamental frequency component is determined. In the nextstage, normalisation processing is executed based on the fundamental periodpreviously determined. The third stage sorts out the signal values needed forcomputation from global signal values. In the fourth and fifth stages, absolutevalue for frequency deviation is computed from the signal values. In the sixth stage,final value of most recent frequency deviation is computed.
