Guard interval and FFT mode detector in DVB-T receiver |
August 18, 2009 |
| For determining FFT and GI (guard interval) modes within a receiver, a correlation signal is generated from an in-phase and quadrature (I/Q) stream. An plurality of GI mode division signals are generated by processing the correlation signal delayed by different delays. For each of th |
