Linear feedback shift register (LFSR)

摘要

A wireless communication device is described. The wireless communication device includes a linear feedback shift register. The linear feedback shift register is initialized. The linear feedback shift register is a word based odd characteristic linear feedback shift register. The linear feedback shift register includes multiple 64-bit registers. A feedback function output is generated using the 64-bit registers. The feedback function output is placed into a highest register of the linear feedback shift register.
