Specify the decision method used for decoding as one of Hard decision | Soft decision . The default is Hard decision . When you set this property to Hard decision , the output is decoded bits of double or logical data type. When you set this property to Soft decision , the output is log-likelihood ratios of double data type.-Specify the decision method used for decoding as one of　Hard decision　|　Soft decision .
