    Phase Shift Keying

    No, I'm quite aware that not all sidelobes can be the same power .... that wouldn't even be the same signal in the end I believe. Ok, I didn't mention that our info. wave (signal ... ) had the freq. of 100KHz (very inconvenient for transmission ergo we modulate it into a carrier wave .... ) But...

    Phase Shift Keying

    So we did some experimental measurements at college involving a carrier sine wave of 2Mhz being modulated using 16PSK and 16QAM modulations. The information wave was a bunch of randomly generated '1' and '0'. We observed the modulated signal via oscilloscope and a spectrum analyzer. This is what...
