Subframe interleaving
View Patent ↗Included are embodiments for subframe interleaving. At least one embodiment of a method includes receiving at least one subframe, the at least one subframe being derived from a plurality of frames of data and interspersing at least a portion of the at least one subframe according to a predetermined subframe interleaving strategy.
1. A subframe interleaver, comprising:
a receiving component that receives a predetermined number of subframes, the predetermined number of subframes being derived from a plurality of frames of data, where the predetermined number is determined from an offline calibration;
a first determining component that determines whether a total number of received subframes does not meet a predetermined threshold; and
an interspersing component that, in response to determining that the total number of received subframes does not meet the predetermined threshold, intersperses at least a portion of the at least one subframe according to a subframe interleaving strategy determined from the offline calibration.
2. The subframe interleaver of claim 1 , further comprising a periodic subframe interleaver input device that forms a symbol associated with an output.
3. The subframe interleaver of claim 1 , further comprising a symbol interleaver device that sends data associated with a symbol.
4. The subframe interleaver of claim 3 , wherein data associated with a symbol includes at least one of the following: the symbol and memory address of the symbol.
5. The subframe interleaver of claim 1 , further comprising an output component that sends the interspersed subframes to a mapper component.
6. The subframe interleaver of claim 5 , wherein the output component further, in response to a determination that the total number of received subframes meets the predetermined threshold, sends the received subframe to a mapper component.
7. The subframe interleaver of claim 1 , wherein the subframe interleaver is configured for implementation with at least one of the following: a set-top box, a television, a portable appliance, a gaming unit, a satellite system, an MP3 player, an IPOD® player, a cellular telephone, a wireless communications device, a Digital Subscriber Line (DSL) modem, and a wireless communications device.
8. A method for subframe interleaving, comprising:
receiving, by a computer, a predetermined number of subframes, the predetermined number of subframes being derived from a plurality of frames of data, where the predetermined number is determined from an offline calibration; and
in response to a determination that a total number of received subframes does not meet a predetermined threshold, interspersing at least a portion of the at least one subframe according to a subframe interleaving strategy determined from the offline calibration.
9. The method of claim 8 , further comprising determining whether to execute a first subframe interleaving strategy, the first subframe interleaving strategy including forming a symbol associated with an output of a periodic subframe interleaver input device.
10. The method of claim 8 , further comprising determining whether to execute a second subframe interleaving strategy, the second subframe interleaving strategy including:
sending a data associated with a symbol to a symbol interleaver device; and
forming a symbol associated with an output of a periodic subframe interleaver input device.
11. The method of claim 10 , wherein data associated with a symbol includes at least one of the following: the symbol and memory address of the symbol.
12. The method of claim 8 , further comprising sending the interspersed subframes to a mapper component.
13. The method of claim 8 , wherein at least a portion of the method is performed in at least one of the following: a set-top box, a television, a portable appliance, a gaming unit, a satellite system, an MP3 player, an IPOD® player, a cellular telephone, a wireline communications device, a Digital Subscriber Line (DSL) modem, and a wireless communications device.
14. A system for subframe interleaving, comprising:
means for receiving a predetermined number of subframes, the predetermined number of subframes being derived from a plurality of frames of data, where the predetermined number is determined from an offline calibration; and
means for, in response to a determination that a total number received subframes does not meet a predetermined threshold, interspersing at least a portion of the at least one subframe according to a subframe interleaving strategy determined from the offline calibration.
15. The system of claim 14 , further comprising means for determining whether to execute a first subframe interleaving strategy, the first subframe interleaving strategy including forming a symbol associated with an output of a periodic subframe interleaver input device.
16. The system of claim 14 , further comprising means for determining whether to execute a second subframe interleaving strategy, the second subframe interleaving strategy including:
sending a data associated with a symbol to a symbol interleaver device; and
forming a symbol associated with an output of a periodic subframe interleaver input device.
17. The system of claim 16 , wherein data associated with a symbol includes at least one of the following: the symbol and memory address of the symbol.
18. The system of claim 14 , further comprising means for sending the interspersed subframes to a mapper component.
19. The system of claim 14 , wherein at least a portion of the system is configured for operation with at least one of the following: a set-top box, a television, a portable appliance, a gaming unit, a satellite system, an MP3 player, an IPOD® player, a cellular telephone, a wireline communications device, a Digital Subscriber Line (DSL) modem, and a wireless communications device.
