Abstract: Provided is a method for mitigating, by an interference mitigation apparatus, interference on a home network transmission line. The method includes pairing domain masters with relay terminals by a signal having a unique frequency, grouping the domain masters, performing Tx/Rx synchronization between the domain masters and the relay terminals, and controlling the domain masters and the relay terminals to transmit/receive data according to the Tx/Rx synchronization. The domain masters of the same groups may be controlled not to simultaneously transmit/receive data.

Abstract: A communication method transmits a detection signal including a valve ID, which is a fixed data string, and detection information, which is a variable data string, performs error detection on the received detection signal, and uses the detection information when there is no error. The communication method generates third data corresponding to the detection information in accordance with a predetermined rule to increase redundancy of the detection information, generates computed data by performing an exclusive disjunction logic operation with the valve ID and data including the detection information and the third data, transmits the detection signal that includes the computed data, receives the detection signal, restores the detection information and the third data by performing an exclusive disjunction logical operation with the received detection signal and the computed data, and determines whether the detection information conforms to the third data.

Abstract: A receiver system for early detection of a segment type of an input signal based on BPSK and DBPSK modulated carriers is provided. The receiver system includes a tuner that converts the input signal into an intermediate frequency (IF) signal, a signal conditioning module that converts the IF signal into a baseband signal, a Frequency Domain Synchronization (FDS) block that detects the segment type of the input signal based on a carrier powers, a Transmission and Multiplexing Configuration Control (TMCC) decode block that performs a decoding operation on the received signal, a channel estimation block that estimates a channel and obtains a channel information. The TMCC decode block uses the channel information obtained from channel estimation block to correct a fast-frequency selective fading on the received signal before the decoding operation.
