Accepts an M-ary value that specifies a predefined symbol map with the number of distinct symbol map values to use as symbols.

## samples per symbol

Number of samples dedicated to each symbol. Multiply this value by the symbol rate to determine the sample rate.

Default: 16

## M-CPM

The M-ary number, which is the number of distinct frequency deviations to use as symbols. This value must be a positive power of 2.

Default: 2

## modulation index, h(i)

Modulation index for the CPM modulation scheme.

Refer to CPM Modulation for more information about modulation indices. The modulation index must be of proper form, that is, the numerator must be lesser than the denominator. The modulation index may vary between symbol intervals.

### numerator

Numerator of the modulation index.

### denominator

Denominator of the modulation index.

## symbol rate

The desired symbol rate, in hertz (Hz).

Default: 1.0

## error in

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

Default: no error

## CPM system parameters

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

### samples per symbol

Number of samples dedicated to each symbol. Multiply this value by the symbol rate to determine the sample rate.

### symbol map

A two-dimensional array of desired frequency deviations. Each column corresponds to a symbol, with the binary representation of the column index being the mapped bit-representation of the symbol. Each row corresponds to a modulation index in the order in which it appears in the modulation index, h(i) parameter of MT Generate CPM System Parameters (M) or MT Generate CPM System Parameters (map).

Default: Empty array

## 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 4-CPM, M = 4).

## error out

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