symbols specifies an array of FSK frequency deviations for one-to-one mapping to the output bit stream based on the symbol map.

symbol map specifies an ordered array that maps each symbol value to its desired deviation frequency. The number of FSK levels in the array must be 2^N, where N is the number of bits per symbol. To specify a prebuilt map, unbundle the symbol map element from the FSK system parameters cluster generated by the FSK (M) or FSK (Map) instance of the MT Generate System Parameters VI.

symbols specifies the incoming complex-valued PSK symbols to be mapped to the output bit stream based on the symbol map.

The number of PSK states in the array must be 2^N, where N is the number of bits per symbol. To specify a prebuilt map, unbundle the symbol map element from the PSK system parameters cluster generated by the PSK (M) or PSK (Map) instance of the MT Generate System Parameters VI.

PSK type specifies the type of phase-shift keying modulation.

normal	Sets the modulation type to regular PSK. This is the default value.
shifted	Rotates the constellation by /M each symbol.
offset	Sets the modulation type to offset quadrature phase-shift keying (OQPSK). This modulation scheme is a form of phase-shift keying in which four different phase angles are used. This scheme is sometimes referred to as staggered quadrature phase-shift keying (SQPSK). For offset PSK, the ideal symbol timing for Q is offset by 1/2 of a symbol period from the ideal symbol timing for I. offset is currently only supported for M = 4.

carrier phase correction specifies the carrier phase correction applied to the symbol array prior to mapping. The correction overcomes the starting phase ambiguity during shifted-PSK demodulation. Use this control when the PSK modulation type is set to shifted and differential PSK is set to disable. The default is 0.0.

differential PSK specifies how the modulation represents symbols. Differential operation is used to implement PSK formats such as differential quadrature PSK (DQPSK) and /4 DQPSK.

reset? specifies whether stored state information is cleared on each call to this VI. When the input bit stream is not comprised of an integer number of symbols, the carryover bits are buffered. When reset? is set to TRUE (default), this buffer is cleared at each call. When reset? is set to FALSE, the carryover bits are added to the beginning of the input bit stream at the next call to this VI. This option is useful when the current block of data is contiguous with the preceding block of data. The default is TRUE.

symbols specifies an array of MSK frequency deviations for one-to-one mapping to the output bit stream.

symbol rate specifies the symbol rate, in hertz, of the symbols data.

Note   For MSK modulation, the frequency deviation is ¼ the symbol rate. For nondifferential MSK, the symbol-to-bit mapping is performed by mapping bit 0 → –0.25 × symbol rate, and mapping bit 1 → +0.25 × symbol rate.

differential encoding enable specifies whether to enable differential encoding of the input symbols prior to mapping to the output bit stream.

reset? specifies whether the carryover bit at the end of differential encoding is added to the beginning of the input bit stream at the next call to this VI. When reset? is set to TRUE (default), the carryover bit is cleared at each call. When reset? is set to FALSE and differential coding enable is set to TRUE (default), the carryover bit is added to the beginning of the input bit stream at the next call to this VI. The default is TRUE.

symbols specifies an array of frequency deviations for one-to-one mapping to the output bit stream based on the symbol map.

symbol map specifies an ordered array that maps each symbol value to its desired deviation frequency. To specify a prebuilt map, unbundle the symbol map element from the CPM system parameters cluster generated by the CPM instance of the MT Generate System Parameters VI.

synchronization parameters specifies parameter values describing the synchronization sequence and the range of bits over which to search for the sequence. Wire the CPM synchronization parameters cluster returned by the CPM bit array or number array instances of the MT Generate Synchronization Parameters VI to this cluster.

Note   If the CPM synchronization parameters cluster is not wired, the demodulator does not attempt to synchronize, and the constellation of the demodulated waveform has a carrier phase ambiguity.

	expected sync location specifies the expected location of the first symbol of the synchronization sequence. This value is an index to the input complex waveform. A value of -1 searches the entire input complex waveform and ignores the sync location uncertainty parameter.
	sync sequence specifies the mapped symbol pattern. Although the data type is complex, only the real portion is used. For CPM, the real portion of the mapped symbols is the frequency deviation of the symbol value, and the imaginary portion is 0. To prevent false synchronization, configure this pattern so that there is a low probability of accidental correlation to nonsynchronized parts of the data stream. If this parameter is left empty, the signal is still demodulated.
	sync location uncertainty specifies the number of symbols before or after the expected sync location where the first symbol of the sync sequence may be located. This parameter is ignored if the expected sync location parameter is set to -1.
	sync indent specifies the distance that the sync sequence is indented into the information block. The distance is the number of demodulated symbols preceding the sync sequence. For example, a value of 10 indicates that the output bit stream consists of 10 data symbols, followed by the sync sequence, followed by the remaining data symbols.
