BPSK Constellation Diagram

  1. Dec 28, 2011 #1
    1. The problem statement, all variables and given/known data

    Design a constellation diagram that supports transmission of complex symbols where for the same
    baud rate, the transmission bit rate of symbols on your constellation should be 5 times the
    transmission bit rate of Binary Phase Shift Keying (BPSK) symbols.

    3. The attempt at a solution

    The simplest PSK is binary PSK, in which we have only two signal elements, one with
    a phase of 0°, and the other with a phase of 180°.

    Constellation Diagram,

    BPSK also uses only an in-phase carrier. However, we use a polar NRZ signal for modulation.
    It creates two types of signal elements, one with amplitude 1 and the other with
    amplitude -1. This can be stated in other words: BPSK creates two different signal elements,
    one with amplitude I V and in phase and the other with amplitude 1V and 1800 out of phase.

    Please give me an idea to start..
