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： A system and method are provided for generating bit log likelihood ratio (LLR) values for two-layered Quadrature Phase-Shift Keying (QPSK) turbo decoding in a wireless communications user terminal (UT). The method includes receiving a two-layered QPSK signal with an energy ratio that is unknown, but typically defined as either k12 or k22. The method selects a mismatched energy ratio (k2) between k12 and k22, and generating bit LLR values for two-layered QPSK turbo decoding, using the mismatched k2 energy ratio. For example, if the received two-layered QPSK signal is known to have an energy ratio of about 4 or about 6.25. Then, k2 is selected to be about 5.0625. Alternately stated, the mismatched k2 energy ratio in selected by determining the approximate midpoint between k12 and k22.
