What is claimed is:
1. A DSL modem apparatus comprising:
a transmitter that transmits a transmission signal to a line, the transmission signal comprising a predetermined number of symbols;
a receiver that performs a demodulation on the transmission signal received from the line for every symbol of the predetermined number, during a transmission of said transmitter, and outputs a demodulated signal;
a retriever that retrieves data from the demodulated signal; and
a freeze processor that freezes the demodulation during a period in which a hybrid echo of the transmission signal is generated.
2. The DSL modem apparatus according to claim 1, wherein said freeze processor freezes the demodulation after counting a predetermined number of symbols from a carrier topology inversion.
3. The DSL modem apparatus according to claim 1, wherein said receiver comprises an AGC controller that performs an AGC on a subsequent reception signal based on a constellation data of the received signal, and wherein said freeze processor freezes the AGC of said AGC controller, the AGC being performed as a demodulation.
4. The DSL modem apparatus according to claim 1, wherein said receiver comprises a CAPC unit that performs a CAPC on a constellation data of the received signal, and wherein said freeze processor freezes the CAPC of said CAPC unit, the CAPC being performed as a demodulation.
5. The DSL modem apparatus according to claim 1, wherein said receiver comprises a timing regenerator that predicts a symbol breakpoint to be used for a current data retrieval, the symbol breakpoint being predicted from a symbol breakpoint used for a previous data retrieval, and regenerates timing for a symbol breakpoint when the current symbol breakpoint is deviated from a prediction, and wherein said freeze processor freezes timing regeneration of said timing regenerator, the timing regeneration being performed as a demodulation.
6. The DSL modem apparatus according to claim 1, wherein said data retriever replaces retrieving data with retrieved data of at least one previous symbol, when the retrieving data is transmitted during the period in which the hybrid echo is generated.
7. A DSL communication apparatus comprising:
a transceiver that performs a handshake step and an initialization step prior to initiating data communication, and encodes transmission data and modulates reception data after the data communication;
a host that manages an operation of said transceiver, inputs transmission data provided from a user terminal to said transceiver, receives reception data received from said transceiver via a line, and outputs the reception data to the user terminal;
an AFE unit that converts transmission data into an analog signal, the transmission data being output to the line by said transceiver, and converts the analog signal received from the line into digital data;
a driver that transmits the analog signal converted by said AFE unit to the line; and
a receiver that receives the analog signal from the line,
wherein said receiver installs the DSL modem apparatus according to claim 1.
8. A reception method for DSL communication comprising:
transmitting a transmission signal to a line, the transmission signal comprising a predetermined number of symbols;
demodulating the transmission signal received from the line for every symbol of the predetermined number during the transmission; and
freezing the demodulation during a period in which a hybrid echo of the transmission signal is generated.
9. A reception method for G.hs communication comprising:
specifying a signal received during a period in which a hybrid echo of a transmission signal from a transmitting terminal is generated, upon performing a carrier topology inversion for data 1 transmission from the transmitting terminal, when a handshake step based on ITU-T recommended G.994.1 (G.hs) is executed; and
freezing a demodulation for the specified signal.
