Embodiment 1
[0029] This embodiment provides an error correction and feedback equalization control method, such as figure 1 shown, including the following steps:
[0030] S101, pre-store the initial value of the training sequence;
[0031] The training sequence may be a string of binary sequences consisting of 0 or 1, and the receiving and transmitting parties agree on the training sequence in advance.
[0032] S102. Compensate the received data information by using an equalization algorithm.
[0033] Here, the compensation method in the prior art may be used to compensate the received data information. The difference is that the received data information carries relevant information of the training sequence and valid data, so the compensated data information will include the soft information of the training sequence and the soft information of the valid data. The valid data is valid data among the data to be sent by the sender, and corresponds to all the data previously sent by the sen...
Embodiment 2
[0069] This embodiment provides an error correction and feedback equalization control device, such as figure 2 As shown, it includes a storage module 10, a compensation module 20, a first calculation module 30, a second calculation module 40, a third calculation module 50, a fourth calculation module 60, a fifth calculation module 70, an adjustment module 80 and an error correction module 90 :
[0070] The storage module 10 is used for pre-storing the initial value of the training sequence.
[0071] The training sequence may be a string of binary sequences consisting of 0 or 1, and the receiving and transmitting parties agree on the training sequence in advance. The storage module 10 may be a memory at the exit of the DSP equalization module, for example, a memory at the exit of the DSP equalizer.
[0072] The compensation module 20 is configured to use an equalization algorithm to compensate the received data information. The compensated data information includes soft inf...
