摘要： A method and an apparatus for creating codes by using an LFSR(Linear Feedback Shift Register) are provided to shorten the time required in calculating the new state of an LFSR by reducing the number of clocks. A control part expresses a characteristic polynomial indicating the present state value of an LFSR as an element of a Galois field "GF(2^n)". The control part expresses the characteristic polynomial as a function for the primitive root of GF(2^n). The control part obtains a characteristic polynomial at an arbitrary time non-fixedly determined from the characteristic polynomial expressed as a function for the primitive root of GF(2^n). The control part repeatedly executes multiplication and squaring for the characteristic polynomial obtained at the arbitrary time, and provides a new LFSR state value so that a code having the new LFSR state value can be created.

摘要： PURPOSE: A method for generating a PN(Pseudo Noise) sequence is provided to generate the PN sequence in a desired delayed state, without requiring an additional hardware logic or large memory. Thus the PN sequence having the desired delay is generated with relatively small amount of computations. CONSTITUTION: Register seed values of PNs delayed at predetermined intervals are stored in a memory in advance. If a desired delay value is applied, a seed value of sequence under the delay value is selected from the memory. The selected seed value is inputted in a register of a PN sequence generator. Sequential operation of the PN sequence generator is performed correspondingly to a delay difference between the applied delay value and the selected seed value sequence. And the seed value indicates a bit string that is inputted to the PN sequence generator register in order to output an n-th sequence.

摘要： PURPOSE: A code generator is provided to minimize the number of components in an equipment used and simplify the structure by using the common elements of the generator for generating both codes. CONSTITUTION: A receiving signal of the GPS and GLONASS SRNS(Satellite Radio-Navigation Systems) is converted a frequency, modulated, and is processed the digital correlation. A generator for generating a code of pseudo-random sequences is used as reference code generators during the digital correlation processing of signals in multi-channel receivers for receiving pseudo-noise signals. The generator for the SNRS operates in two modes, i.e. a mode for generating a code of pseudo-random sequences for the GPS system and a mode for generating a code of pseudo-random sequences for the GLONASS system. This result can be achieved by an optimization of the connection and interaction between the standard components of the generator.

摘要： PURPOSE: A method for generating a pseudo random sequence in a wireless communication system, is provided to generate the pseudo random sequence using binary data generated by repeatedly multiplying an optional input integer by binary parallel data of a tuple, so as to easily implement a scrambler and a de-scrambler with a simple digital logical circuit and a register. CONSTITUTION: Initial data of a tuple is previously generated, and an optional random integer is inputted for deciding a pseudo random sequence finally generated. Whether the inputted integer is capable of generating a sequence satisfying entire period is confirmed. The first tuple multiplication is repeatedly performed by using the initial data of the tuple and a normal basis of a time origin, according to whether the greatest common measure between an entire period value and the inputted integer is a predetermined value, to calculate a conjugate group for an inputted time origin. Coefficient values are calculated in the first tuple type of a minimum polynomial in a Galois field for the inputted time origin. Mapping data in a predetermined second tuple type corresponding to each coefficient value are decided. An input value for the multiplication with the second tuple of data is calculated. A calculation value fed back according to predetermined clocks and the second tuple of data are multiplied. The second tuple of data are inputted, to generate a predetermined bit of pseudo random sequence.

摘要： A CDMA baseband modern having a PN generator with significant reduction in stored masks is disclosed. Various performance matrices set forth alternative combinations of sequence generation through three parameters: storage, software, and time. Embodiments of this implementation are presented with corresponding hardware complexities. Masks are used to move to a new phase offset sequence. Instead of storing 2Nmasks, less than N masks are required to be stored in ROM because of mask calculation intelligence carried out in the software/software control. Masks are calculated with a mask generating polynomial based upon any degree of characteristic polynomial of a PN generator. Masks for the mask generator are only stored which result in phase shifts of powers of two. The characteristic polynomial of the pseudo-random noise generator and the mask generator are Galois and Fibonacci polynomials.
