In Quadrature Phase Shift Keying (QPSK) two sinusoids (sin and cos) are taken as basis functions for modulation. Modulation is achieved by varying the phase of the basis functions depending on the message symbols. In QPSK, modulation is symbol based,where one symbol contains 2 bits. The following equation outlines QPSK modulation technique. s i ... This paper presents an efficient approach for the implementation of typical communication structures studied in class. This scheme is beneficial where the objective is to implement the physical working of complex DSP or communication structures or

The MATLAB vari-able no samples speciﬁes number of samples to be generated using rand function. i.e., no samples = 3*105. (correct option iii.) 2.The baseband QPSK modulated signal s can be generated using the MATLAB com-mand: Solution: Since baseband QPSK signal is complex, it can be ... Input signal, specified as a scalar, vector, matrix, or 3-D array. The elements of x must be binary values or integers that range from 0 to (M – 1), where M is the modulation order.

Oct 26, 2011 · Complex numbers are used to model the in-phase and quadrature components of a QPSK signal. The length of the symbol sequence and range of EbNo can be varied. Cite As
