Energy dispersal circuit and receiver

摘要

An energy dispersal circuit, which generates a PRBS (Pseudo Random Binary Sequence) and executes an XOR (exclusive-OR) operation with respect to a data signal and the PRBS based on a bit, includes a register value calculator for calculating a register value of a shift register based on inputted data and a packet number. The register value calculator has a bit divider for dividing the packet number from LSB to MSB, packet shift operators for bit-shifting an initial value of the shift register from 2 0 bits to 2 N-1 bits, and selectors for selecting inputs and outputs thereof.
