Characteristic information of GPU-based Viterbi decoder
Get Characteristic Information of GPU-based Viterbi Decoder
Create a GPU-based Viterbi decoder System object™ that accepts an input vector of hard decision values, which are zeros or ones.
gpuVitDec = comm.gpu.ViterbiDecoder('InputFormat','Hard');
Get the characteristic information of the GPU-based Viterbi decoder.
infostruct = info(gpuVitDec)
infostruct = struct with fields: AcquisitionDepth: 70
infostruct — Characteristic information
Characteristic information of the input GPU-based Viterbi decoder, returned as a structure that contains this field.
AcquisitionDepth — Acquisition depth used in GPU implementation
Acquisition depth used in the GPU implementation, returned as an integer.
The acquisition depth is the number of depunctured codewords that are used to
overlap subsequences of the received data in the GPU implementation of the Viterbi
decoder. For unpunctured codes,
AcquisitionDepth is the greater
of ten times the constraint length or two times the
TracebackDepth property of the decoder. For punctured
AcquisitionDepth is scaled by a multiple of the number
of codewords in the puncture pattern vector.
