Abstract :
We experimentally de-aggregate the 8-PSK signal (EVM 8.7%) onto two 4-PAM signals (EVM 8.8%). QPSK signals are demultiplexed into two BPSK signals with EVMs ~11.4 %. De-aggregation performance as a function of the OSNR of the incoming signals is evaluated. The effect of phase noise is also studied.
