To compress data, the LZ77 algorithm replaces portions of the data with references to matching data that has already passed through both the encoder and the decoder.
This blind equalization algorithm can work with a noncoherent decoder, resulting in a low-complexity and completely blind method for decoding in the present of ISI.
这种均衡器可以和非相干检测器配合使用，从而在存在码间干扰的情况下实现低复杂度的完全盲均衡。

With the development of LDPC algorithm which has a hardware-friendly trend, the VLSI realization of LDPC decoder is becoming ever the focus of researchers.
