Receiving apparatus and method for detecting the number of bits of the same value in a received bit stream

摘要

An edge interval measuring block measures a first same-edge interval. A bit number detector detects the number of bits in the first same-edge interval based on reference bit length information and detects a first number of bits in a same-value interval between consecutive bits of the same value by subtracting the number of bits in the known bit stream from the number of bits in the first same-edge interval. The edge interval measuring block then measures a second same-edge interval. The bit number detector detects the number of bits in the second same-edge interval based on the reference bit length information and detects a second number of bits in a bit stream of consecutive bits of the same value opposite to the value in the same-value interval by subtracting the first number of bits from the number of bits in the second same-edge interval.

1. A receiving apparatus comprising:
an edge interval measuring block that measures a first same-edge interval from when a first start edge indicative of a start of a known bit stream of consecutive bits of a same value in a received bit stream is detected to when a next edge changing in a same direction as the first start edge is detected; and a bit number detector that detects a number of bits in the first same-edge interval based on reference bit length information and detects a first number of bits in a same-value interval between consecutive bits of a same value by subtracting a number of bits in the known bit stream from the number of bits in the first same-edge interval, wherein the edge interval measuring block measures a second same-edge interval from when a second start edge indicative of a start of the same-value interval is detected to when a next edge changing in a same direction as the second start edge is detected, and the bit number detector detects a number of bits in the second same-edge interval based on the reference bit length information and detects a second number of bits in a bit stream of consecutive bits of a same value opposite to the value in the same-value interval by subtracting the first number of bits from the number of bits in the second same-edge interval.
