Abstract
Disclosed herein are a synchronization apparatus and method for a upstream system. The synchronization apparatus for a upstream system includes one or more processors, and execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to receive a signal and calculate a first channel estimation value for the received signal using a predefined pilot, and calculate a second channel estimation value using a predefined complementary pilot and the first channel estimation value.
Claims10
A synchronization apparatus for an upstream system, comprising:
- one or more processors;
- and
- an execution memory for storing at least one program that is executed by the one or more processors,
- wherein the at least one program when executed causes the one or more processors to:
- receive a signal and calculate a first channel estimation value for the received signal using a predefined pilot, and
- calculate a second channel estimation value using a predefined complementary pilot and the first channel estimation value,
- wherein the at least one program when executed further causes the one or more processors to extract a compensation parameter from a preset symbol range in a symbol constellation from which the predefined complementary pilot is extracted.
(canceled)
A synchronization method for an upstream system, the synchronization method being performed using a synchronization apparatus for the upstream system, the synchronization method comprising:
- receiving a signal and calculating a first channel estimation value for the received signal using a predefined pilot;
- and
- calculating a second channel estimation value using a predefined complementary pilot and the first channel estimation value,
- wherein calculating the second channel estimation value further comprises extracting a compensation parameter from a preset symbol range in a symbol constellation from which the predefined complementary pilot is extracted.
