MT Map Bits to PAM Symbols
Maps an incoming bit stream to complex-valued PAM symbols.
Inputs/Outputs

input bit stream
The incoming bit stream to be mapped to symbols.

symbol map
An ordered array that maps each symbol value to its desired coordinates in the complex plane.
The number of PAM states in the array must be 2N, where N is the number of bits per symbol. The length of the vector for the symbols farthest from the origin must be 1. To specify a prebuilt map, unbundle the symbol map element from the PAM system parameters cluster generated byMT Generate PAM System Parameters (M) or MT Generate PAM 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 value: No error

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 value: TRUE

symbols
An array of complex-valued symbols with a one-to-one mapping to the input bit stream based on the specified symbol map.

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