Multi-Standard Scramble Code Generation Using Galois Field Arithmetic

This invention is a method of using a Fibonacci form linear feedback shift register. The Fibonacci form linear feedback shift register having an initial state and a set of taps is converter into an equivalent Galois form linear feedback shift register. The Galois form linear feedback shift register state is altered employing Galois field arithmetic. The altered Galois form linear feedback shift register is converted into an equivalent altered Fibonacci form linear feedback shift register. A pseudo-random number produced by the altered Fibonacci form linear feedback shift register is used, for example in a scramble code.
