Abstract
Apparatuses, systems, and techniques to decode encoded data for fifth-generation (5G) new radio (NR). In at least one embodiment, a processor includes one or more circuits to select one or more data decoding operations to decode one or more 5G signals based, at least in part, on a sparsity of data received by the processor.
Claims27
A processor, comprising:
- one or more circuits to select one of a plurality of Fifth Generation (5G) signal decoding operations based, at least in part, on a sparsity of error correction information associated with the 5G signal, wherein the 5G signal decoding operation is a low density parity check (LDPC) decoding operation, and the one or more circuits are to select a first type of LDPC decoding operation in response to the sparsity of error correction information is less than or equal to a predefined threshold value, and are to select a second type of LDPC decoding operation in response to the sparsity of error correction information is greater than the predefined threshold value, where the error correction information is represented using a quasi-cyclic LDPC (QC-LDPC) base graph.
A system, comprising:
- one or more processors to select one of a plurality of Fifth Generation (5G) signal decoding operations based, at least in part, on a sparsity of error correction information associated with the 5G signal, wherein the 5G signal decoding operation is a low density parity check (LDPC) decoding operation, and the one or more processors are to perform a first type of data decoding operation in response to the sparsity of error correction information is less than or equal to a predefined threshold value, and are to perform a second type of data decoding operation in response to the sparsity of error correction information is greater than the predefined threshold value.
A non-transitory machine-readable medium having stored thereon a set of instructions, which if performed by one or more processors, cause the one or more processors to at least:
- select one of a plurality of Fifth Generation (5G) signal decoding operations based, at least in part, on a sparsity of error correction information associated with the 5G signal, wherein the set of instructions, which if performed by the one or more processors, further cause the one or more processors to perform the selected 5G signal decoding operation based, at least in part, on using a circulant matrix and a set of log likelihood ratio (LLR) input data.
A method, comprising:
- selecting one of a plurality of Fifth Generation (5G) signal decoding operations based, at least in part, on a sparsity of error correction information associated with the 5G signal, wherein a first type of low density parity check (LDPC) data decoding operation is selected in response to the sparsity of error correction information is less than or equal to a predefined threshold value, and a second type of LDPC data decoding operation is selected in response to the sparsity of error correction information is greater than the predefined threshold value.
