Detection and removal of clipping in multicarrier receivers |
| 摘要 |
<p>A COFDM receiver includes a tuner/demodulator (34), an analog-to-digital converter (36), an impulse processor (38), and an OFDM demodulator (40). The impulse processor detects digital values which equal the clipping level in the ADC, and assumes that these represent impulsive interference. These samples are then replaced by samples of zero value. <IMAGE></p> |
