Array of symbol values with an order that corresponds to the symbol map. The number of FSK levels specified in the array must be 2 N , where N is the number of bits per symbol.
This parameter expects an array of integers. The integers 0 to (M-1), inclusive, must all be included only once in the symbol values array, where M is the M-ary number of the modulation. The symbol locations (FSK frequencies) are evenly spaced between -FSK Deviation and +FSK Deviation, inclusive, with the binary representation (LSB first convention) of the integers that populate the symbol values array that corresponds to the placement of the M-ary bits on the I/Q constellation.
For example, for 4-FSK, if you specify FSK deviation as 150k and symbol values as [0 1 3 2], then:
00 (symbol value 0) corresponds to -150k
01 (symbol value 1) corresponds to -50k
11 (symbol value 3) corresponds to 50k
10 (symbol value 2) corresponds to 150k
Therefore the generated FSK symbol map reads [-150k -50k 150k 50k]. Similarly, if you specify the symbol values array as [0 1 2 3], the generated FSK symbol map reads [-150k -50k 50k 150k].
