MT Map Bits to FSK Symbols (G Dataflow)

Last Modified: January 9, 2017

Maps an incoming bit stream to symbols comprised of FSK frequency deviations.

input bit stream

The incoming bit stream to be mapped to symbols.

datatype_icon

symbol map

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 MT Generate FSK System Parameters (M) or MT Generate FSK System Parameters (map).

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

reset?

A Boolean that determines whether stored state information is cleared on each call to this node.

When the input bit stream is not comprised of an integer number of symbols, the carryover bits are buffered.

TRUE Clears the buffered data, checks the input parameters on a first call, and reflects any change in the input parameter values during subsequent iterations.
FALSE Adds the buffered data to the beginning of data from next iteration, in continuous operations.

Default: TRUE

datatype_icon

symbols

An array of FSK frequency deviations with a one-to-one mapping to the input bit stream based on the specified FSK symbol map.

Wire this parameter to MT Apply Pulse Shaping Filter (FSK) to generate the oversampled baseband complex waveform.

datatype_icon

error out

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

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported
