Modulator.zip - The following two MATLAB functions show how you can easily implement
the LTE modulation and demodulation algorithms, with all their specifications, using System
objects of the Communications System Toolbox
The Modulator function has two input arguments: the input bit stream (u) and a parameter
representing the modulation mode (Mode). As its output, the function computes the modulated
symbols. The function implements the three different types of modulator used in the LTE
standard. For example, in the case of QPSK, we use a comm.PSKModulator System object
and set its modulation order to 4. Similarly, in the case of 16QAM and 64QAM we use the
comm.RectangulatQAMModulator System objects and set their modulation orders to 16 and
64, respectively. Depending on the value of the modulation mode, we process the input bits to
generate the modulated symbols as the output.,2016-03-07 19:14:00,下载6次
