Embodiment Construction

[0086] figure 1 Shown is the designed multi-mode configurable FEC decoder compatible with LDPC code and Turbo code. Among them, the dark part represents the memory, the rest is the logic module, and the dotted line part is the control part of the whole decoder. The decoder contains a large amount of memory, a very flexible permutation network, a configurable calculation unit SISO capable of supporting two kinds of error correction code logic operations at the same time, and a global control unit. Among them, the memory can be further divided into a memory array required for iteration, a channel information memory, a buffer for preventing memory access conflicts, an intermediate temporary storage unit FIFO / LIFO, and a hard judgment information memory. The permutation network not only needs to support LDPC configurable cyclic shift, but also needs to support the conflict-free QPP interleaver of Turbo codes. The SISO module needs to complete the forward and backward updates of ...

Abstract

The invention belongs to the technical field of wireless digital communication and broadcast, and particularly relates to a high-performance multistandard FEC (Forward Error Correction) decoder. The decoder is flexible and configurable, and can be simultaneously compatible with multistandard and multimode of a LDPC code and a Turbo code. The decoder can meet the requirements of high throughput rate and low power consumption of a current communication system, can enable a designed structure to have higher structure configurability simultaneously, and can be very easily applied in different communication standards. The decoder can support WiMAX and WMAN WLAN (Wireless Local Area Network) broadband access technology and an LTE standard of 4G mobile communication. The decoder works at an LDPC decoding mode in a WiMAX and a WLAN, and works at a Turbo decoding mode in LTE communication. Designed error correcting codes can be used for decoding all 114 modes in the WiMAX, all 12 modes in the WLAN and all 188 modes in LTE.

Description

technical field [0001] The invention belongs to the technical field of wireless digital communication and broadcasting, and in particular relates to a high-performance multi-standard FEC decoder. Background technique [0002] Since the 1990s, human society has entered a stage of rapid development of digitization and informationization. Due to the different social environments and the rapid development of information science and technology, various digital communication technologies are constantly emerging in various fields of society, and people's pursuit of high-speed and reliable communication systems is also increasing. These communication standards are divided according to application fields, including 3GPP-LTE, GSM, TD-SCDMA, etc. applied to mobile communications; IEEE 802.11n, IEEE 802.16e, etc. applied to broadband wireless communications; and DVB- S2, DTMB, etc. There are so many types of communication standards, but people are gradually pursuing the ability to rec...
