Television receivers and methods for processing signal sample streams synchronously with line/frame patterns |
摘要 |
<p>Television receivers receive a television signal and downconvert the television signal to generate a complex baseband signal. The complex baseband signal is differentiated and then integrated to reduce a direct current (DC) offset in the complex baseband signal. The television receiver may include a periodic known information field. The known information field is correlated with the integrated signal to determine a residual offset therein that is associated with a constant used in integrating the differentiated complex baseband signal. The residual offset is subtracted from this constant when integrating the differentiated complex baseband signal.</p> |
