Description Usage Arguments Value See Also Examples
Receives a vector of bits (1's and 0's). The received vector is mapped to in-phase (real) and quadrature (imaginary) components, according to a Binary Reflective Gray Code (BRGC, see reference). Each received pair of bits are are mapped to 8-PSK symbols, with sqrt(Es) (symbol energy) = 1.The bit to symbol mapping is illustrated in the following constellation diagram.
input | output |
000 | 0 |
001 | π/4 |
011 | π/2 |
010 | 3 π/4 |
110 | pi |
111 | -3 π/4 |
101 | - π/2 |
100 | - π/4 |

1 | f8pskmod(bits, Ns = 1, p = 1)
|
bits |
vector of bits (0's and 1's). |
Ns |
N samples per symbol (default, Ns = 1) |
p |
a vector defining the pulse shape of the transmitted waveform (default, p = 1) |
Returns a complex vector of length = (length(bits) mod 3), 8-PSK symbols. If Ns > 1 then the returned signal is shaped with pulse shape, p.
