SIMULASI PEMBANGKITAN SINYAL 8–PHASE SHIFT KEYING BERBASIS MATLAB
Abstract: Phase Shift Keying
(PSK) is simply the allocation of one fixed phase for every code in the bit
streams. In BPSK modulation, it’s needed to allocate two distinct phases for
“1” and “0”. In QPSK modulation, it’s needed to allocate four distinct phases,
each for “01”, “01”, “10”, and “11”. While in 8 – PSK, it’s needed to allocate
eight distinct phases, each for “000”, “001”, “010”, “011”, “100”, “101”,
“110”, and “111”. Bandwidth efficiency in BPSK is 1 b/s/Hz and 2 b/s/Hz in
QPSK. While in 8 – PSK, bandwidth efficiency achieved is 3 b/s/Hz. Higher
efficiency bandwidth means narrower bandwidth needed for data
transmission. This simulation is used to
generate 8 - PSK signals using Matlab software tools. The results show that the
simulation is able to generate BPSK and QPSK signals perfectly.
