QAM modulation scheme is preferable because it provides larger bandwidth and includes two dimensional multi-level coding which has advantage of larger noise margin as compared to single dimensional multi-level coding (Youssef et al., 2013).

* 256 QAM enables customers' devices and the network to exchange information in larger amounts delivering more bits of data in each transmission.
It is a great privilege and the QAM represents the pinnacle of my ambulance career.
The Hermitian symmetry is imposed on subcarriers to generate real OFDM signal by imposing the following relation on the loaded QAM symbols [9]:
The sequence of corrupted received QAM symbols in [S.sub.Tx](t) is denoted by vector [mathematical expression not reproducible].

Con ayuda de LabVIEW, se ejecuta el proceso de modulacion QAM en un bloque que recibe el stream de bits provenientes de la etapa de codificacion.
Qatar Academy Msheireb (QAM) recently hosted its annual 'Back to School Night' to provide parents and teachers with the opportunity to discuss the upcoming academic year and how to enrich the students' overall learning experience, while encouraging their academic and personal development.
The filter bank multicarrier on offset QAM (FBMC/OQAM) system is an alternative multicarrier modulation which does not need the cyclic prefix (CP) or guard interval in orthogonal frequency division multiplexing on QAM (OFDM/QAM) system [1] which is widely used in mobile communication [2] and digital broadcasting transmission system [3].
Under this study, Phase Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM) based symbol mapping/de-mapping schemes were used.
In this paper, we have applied maximum likelihood estimation for systems employing square or cross QAM signals which are undergoing slow flat Rayleigh fading.
