摘要： A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

摘要： A satellite communications system can use a spread-spectrum waveform and format, a synchronization scheme, and/or a power management algorithm. This approach can provide benefits such as allowing every terminal to communicate with every other terminal, link margin permitting. This gives the network a mesh topology although it can be configured in a star topology for highly asymmetric applications. A further understanding of the nature and the advantages of particular embodiments disclosed herein may be realized by reference of the remaining portions of the specification and the attached drawings.

摘要： Disclosed is a method for generating a sequence and an apparatus for the same which can satisfy the number M′ of sequences sufficiently larger than a length N of a sequence required in a wireless communication system. When the generation of a sequence of the wireless communication system is intended, a first sequence is generated from an mth order primitive polynomial determined according to the length of a required sequence. Then, a second sequence and a third sequence are generated from the first sequence, and a remainder and a quotient is obtained by dividing a particular reference parameter by a number equal to or smaller than 2m+1. Next, a fourth sequence having a desired length N is generated by using the remainder and the quotient. Therefore, it is possible to generate sequences satisfying that the number M′ of sequences is sufficiently larger than a length N of the sequence.

摘要： An apparatus and method for generating a scrambling code in a radio communication system is disclosed. In particular, an apparatus and method for generating a scrambling code using a Gold-like sequence even when m is a multiple of 4 for a length 2m−1 of a pseudo-random sequence is disclosed. Two LFSRs (LFSR a and LFSR a′) for generating the Gold-like sequence by two different polynomials of degree m are included. The LFSR a′ is constructed by a reciprocal primitive polynomial of the primitive polynomial of degree m over GF(2) used to construct the LFSR a. In order to generate 2m different scrambling codes, one fixed initial value is input to the LFSR a and different initial values of m bits are input to the LFSR a′ according to system-specific information.
