ELECTRONIC DEVICE AND NOISE-CANCELLATION METHOD |
| 摘要 |
The present invention provides an electronic device including a coupler, a noise-estimation apparatus and an assembly unit. The coupler receives a baseband signal. The noise-estimation apparatus receives the baseband signal and subtracts a predetermined synchronization preamble from the baseband signal to obtain a noise-estimation signal, and the predetermined synchronization preamble is a transmission signal that conforms to the standards of 802.11bg and/or IEEE 802.11n. The assembly unit receives the baseband signal and subtracts a noise-estimation signal from the baseband signal to obtain an output signal. |
