Calculates parameters for use with either MT Modulate MSK or MT Demodulate MSK.

datatype_icon

samples per symbol

An even number of samples dedicated to each symbol. Multiply this value by the symbol rate to determine the sample rate.

Note  

The demodulation and detector nodes use timing recovery, which is optimized for four or more samples per symbol.

Default: 16

datatype_icon

differential encoding enable

A value that indicates whether to enable differential encoding of the bit stream.

disable

Disables bit stream encoding.

enable

Enables bit stream encoding.

Default: enable

datatype_icon

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: no error

datatype_icon

MSK system parameters

Parameter values defining the MSK system. Wire this parameter to the corresponding system parameters cluster of MT Modulate MSK or MT Demodulate MSK.

datatype_icon

differential encoding enable

A value that indicates whether to enable differential encoding of the bit stream.

disable

Disables bit stream encoding.

enable

Enables bit stream encoding.

Default: enable

datatype_icon

samples per symbol

Number of samples per symbol in the modulated output complex waveform.

For error-free operation, the samples per symbol must be an even number. Applying Carson's rule for MSK modulation [peak frequency deviation = 0.25 × symbol rate (Hz)], the 98% MSK bandwidth is given by 0.5 × (1 + r) × symbol rate + peak frequency deviation, where 0 < r ≤ 1 is the filter parameter. To satisfy Nyquist criterion, a good guideline is given by samples per symbol = 2 × ceil(1.5 × bandwidth/symbol rate) to obtain 3× oversampling.

Default: 16

datatype_icon

bits per symbol

Number of bits represented by each symbol. This value is equal to Log 2 (M), where M is the order of the modulation (for example, for 16-MSK, M = 16).

datatype_icon

error out

Error information. The node produces this output according to standard error behavior.
