Code sequence generator.

摘要

A code sequence generator having a register (5) for holding n-bit code, and a calculation circuit (6) for performing matrix calculation on the content of the register (5), and sequentially generating a code sequence by feeding back the calculation results to the register. The matrix which is set in the calculation circuit (6) is changed by selectively reading a matrix from a memory circuit (7) that stores precalculated matrices. This makes it possible to set a desired register state in a short time even if the desired code sequence is very long, and to generate any code sequences without changing the rate of a clock signal.
