Problems solved by technology

However, due to the mutual influence of the functional blocks, during the training process, one often loses sight of the other, so that the parameters of each functional block cannot converge to an appropriate value at the same time, so that the receiver cannot correctly receive the signal from the transmitter

Embodiment Construction

[0036] figure 2 It is a block diagram of an embodiment of the communication system of the present invention, wherein the communication system 20 is a multi-channel communication system, which includes multiple pairs of first transceivers and second transceivers (four pairs are taken as an example in the figure), Each pair of first and second transceivers communicates simultaneously via a separate channel. Before communication, the communication system 20 executes an automatic coordination (auto-negotiation) program to determine the master transceiver and the slave transceiver, for example, the first transceiver is the master transceiver, and the second transceiver It is a slave transceiver, or the second transceiver is the master transceiver, and the first transceiver is a slave transceiver. image 3 It is an internal structure diagram of each transceiver, wherein each transceiver includes a receiver 3 and a transmitter 4 . The transmitter 4 includes a digital signal proces...

Abstract

The invention discloses a transceiver in a communication system and a starting method thereof. The transceiver comprises an automatic synchronization circuit, a time sequence return unit, an interference elimination module and a balancer; the automatic synchronization circuit is used for carrying out automatic synchronization procedures to determine whether the transceiver is a main transceiver or a driven transceiver; when the transceiver is the driven transceiver, the transceiver carries out first stage and second stage when being started; in the first stage, channel estimation is carried out to generate a channel estimation value, parameters of the balancer are preset according to the channel estimation value, and the time sequence return unit and the balancer are trained; and in the second stage, the interference elimination module is trained.

Description

technical field [0001] The invention relates to a communication system, especially a transmitter and receiver in the communication system and its starting method. Background technique [0002] In a general communication system, in order to receive data correctly at the receiving end, the receiver usually includes the following functional blocks: an equalizer, a timing recovery circuit, an interference canceller, and the like. In the startup procedure of the communication system, it is necessary to properly set many internal parameters of these functional blocks in order to make them operate correctly so that the receiver can receive data correctly. In order to properly set these operating parameters, it is usually necessary for the transmitter to transmit known signals, that is, to use a data-directed method to enable the receiver to gradually find the appropriate operating parameters of these functional blocks. [0003] However, in some communication systems, such as IEEE ...
