    摘要： Methods and systems are described for scheduling data in an FLO system. The method may include turbo encoding the data, and dividing a packet of the turbo-coded data into a plurality of subpackets. The method may include scheduling the turbo-coded packet of data so as to distribute the data across multiple frames of a superframe, by transmitting each one of the subpackets during a different frame of the superframe to increase time diversity. The turbo-coded packet of data may comprise systematic bits and parity bits. The method may include separately scheduling the systematic bits and the parity bits during different frames of the superframe.

    摘要： An acquisition module includes a coherent correlator configured to receive a transmission having a pilot signal and correlate the received transmission with a local copy of the pilot signal to produce a first output, a delayed correlator configured to delay the first output and correlate the first output with the delayed first output to produce a second output, and a detector configured to detect the pilot signal in the transmission based on the second output.
