Because no noise is present, you can recover the original data without errors by assigning the negative values to a logical 1 and the positive values to a logical 0.

Semantic Scholar estimates that this publication has 52 citations based on the available data. When the demapping type is set to 'hard'the noise variance estimate is not required and therefore is ignored.
CiteSeerX — A Universal Low-Complexity Symbol-to-Bit Soft Demapper
Number of coded bits per subcarrier per spatial stream, specified as log2 Mwhere M is the modulation order. The first column is mapped with a Demzpper modulation. Because the default demapping type is soft, the output is a vector of soft bits. Input sequence of received symbols, specified as a numeric vector, matrix, or multidimensional array of integers. Translated by Mouseover text to see original.
Specify the size of the constellation rotation as the number in columns of the input sequence. To de-rotate the constellation, specify the same phase as in the mapping function. This is machine translation Translated by.

Perform the constellation demapping with an estimated variance noise equal to zero no added noise. MathWorks does not warrant, demappeg disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation. The size of the output returned equals the size of the input sequence divided by eight.

A Universal Low-Complexity Symbol-to-Bit Soft Demapper
Pre-shared key Pulse-width demappdr Elegant degradation. It can be 'hard' for hard-decision demapping or 'soft' for the soft-decision approximate LLR method. The received symbols must be generated with one of these modulations: Perform a QAM demapping by using hard demodulation. The output is a vector of soft bits ready to be the input of a convolutional decoder. This page has been translated by MathWorks.
Constellation Demapping with Hard Demodulation. In other words, you can convert the soft bits into hard bits.
To derotate the constellation, specify the same phase as in the mapping function. When one of the dimensions of sym is equal to 1, and the corresponding dimension of phase is larger than 1, then the output dimensions have the same size as the dimensions of phase.
