Example Embodiment
[0055] Example one:
[0056] The resource optimization method in baseband processing provided by the embodiment of the present invention is applied to the transmitting end of the DVB-T2 system. The method combines the cell interleaving module and the time interleaving module of the transmitting end of the DVB-T2 system into one. Reduce RAM usage in the system implementation.
[0057] figure 2 This is a schematic flowchart of a resource optimization method in baseband processing provided by an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:
[0058] Step S201: Obtain data to be transmitted.
[0059] The data to be transmitted is composed of multiple cells, which can be data output after constellation rotation, or data output after serial-to-parallel conversion, which is not limited here.
[0060] Step S202: Write the above-mentioned data to be transmitted into RAM according to the writing rule of cell interleaving.
[0061] The w...
Example Embodiment
[0120] Embodiment two:
[0121] Corresponding to the method in the first embodiment, the embodiment of the present invention also provides a resource optimization device in baseband processing, which is also applied to the transmitting end of the DVB-T2 system, such as Figure 8 As shown, the device includes a cell interleaving and time interleaving fusion module 80, and the cell interleaving and time interleaving fusion module 80 includes:
[0122] The data acquisition unit 81 is configured to acquire data to be transmitted;
[0123] The writing unit 82 is configured to write the above data to be transmitted into the RAM according to the writing rule of cell interleaving;
[0124] The reading unit 83 is configured to read the written data to be transmitted from the RAM according to the output rule of time interleaving.
[0125] In the embodiment of the present invention, the data to be transmitted is acquired first, then the data to be transmitted is written into the RAM according to t...
Example Embodiment
[0131] Embodiment three:
[0132] See Picture 10 An embodiment of the present invention also provides an electronic device 100, including: a processor 1001, a memory 1002, a bus 1003, and a communication interface 1004. The processor 1001, the communication interface 1004, and the memory 1002 are connected through the bus 1003; the processor 1001 uses The executable module stored in the memory 1002 is executed, such as a computer program.
[0133] The memory 1002 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the network element of the system and at least one other network element is realized through at least one communication interface 1004 (which may be wired or wireless), and the Internet, wide area network, local network, metropolitan area network, etc. may be used.
[0134] The bus 1003 may be an ISA bus, a PCI bus...
