TIMING SYNCHRONIZATION APPARATUS AND METHOD FOR MULTI-CARRIER MODULATION SIGNALS |
摘要 |
Embodiments of the present invention provide a timing synchronization apparatus and method for multi-carrier modulation signals. Wherein the apparatus includes: a predicting unit configured to denoise delay of symbols received before a currently received symbol, and to predict delay of the currently received symbol or of a symbol received after the currently received symbol according to the denoised symbol delay and a sampling clock frequency offset; and a timing synchronization unit configured to perform timing synchronization according to a predicted value of the delay of the currently received symbol or of the symbol received after the currently received symbol. With the apparatus and method, a signal to noise ratio of multi-carrier modulation signals may be effectively improved, and an effect of a timing error on a communication system may be lowered, thereby improving performance of the communication system. |

1. A timing synchronization apparatus for multi-carrier modulation signals, comprising:
a predicting unit configured to denoise delay of symbols received before a currently received symbol, and to predict a predicted delay of the one of the currently received symbol and a symbol received after the currently received symbol according to a denoised symbol delay and a sampling clock frequency offset; and a timing synchronization unit configured to perform timing synchronization according to a predicted value of the predicted delay of one of the currently received symbol and the symbol received after the currently received symbol. |
