Abstract
For some applications such as mobile communication or transmission of multimedia data, it is desirable to use modems with variable constellation schemes to adapt to the fast changing channel to accommodate a wide range of data transmission rates, bit error rates and data types. In this research we are interested in designing receivers which can identify the QAM constellation schemes from the received signal with an unknown reference phase. The problem is modeled as an M-ary hypothesis test with each hypothesis corresponding to one of the M possible constellation schemes. We show the performance of BPSK, QPSK, 8-PSK, 16-PSK, V.29-7200 bps, V.29-9600 bps, 16-QAM, 32-QAM, 64-QAM, 128-QAM, and 256-QAM classifiers in numerical experiments.
