Embodiment Construction
[0104] Embodiment, see Fig. 1 shown, figure 1 Only the case of one carrier frequency is given.
[0105] A kind of interference iterative elimination system based on cross-correlation and LMS of the present invention comprises:
[0106] An analog-to-digital conversion processing unit 11, which is used to digitize the analog intermediate frequency signal;
[0107] A first complex frequency mixing processing unit 12, which is used to generate the required frequency and perform channel mixing;
[0108] A digital down-conversion processing unit 13, which is used for channel extraction and filtering;
[0109] an LMS processing unit 2: it is used for adaptive echo cancellation processing;
[0110] A digital up-conversion processing unit 14, which is used for up-converting the low-rate baseband signal to an intermediate frequency;
[0111] A second complex frequency mixing processing unit 15, which is used to generate the required frequency and perform channel mixing;
[0112] A ...
