Title:
PSEUDO NOISE CODE GENERATOR
Document Type and Number:
Japanese Patent JPH10257023
Kind Code:
A
Abstract:
To provide a pseudo noise code generator by which a pseudo noise code with an object phase is set at a high speed.
A C/A code generator 9 has a G1 code register 13, a G2 code register 14 and 10-bit shift registers 15, 16. G1, G2 codes in an object phase state are stored in the G1 code register 13 and the G2 code register 14. Data corresponding to the G1, G2 codes from the G1 code register 13 and the G2 code register 14 are stored in the 10-bit shift registers 15, 16. Upon the receipt of a TAP command signal, A C/A code based on the data of the 10-bit shift registers 15, 16 is generated in response to the command.
