-The figure below shows a QPSK transmission model with the pulse shaping filters. Since pulse shaping filters are often distributed as a matched pair between transmitter and receiver, we use the filter shape of ‘Square root’(([[http://en.wikipedia.org/wiki/Root-raised-cosine_filter|Root-raised-cosine filter]])).+The figure below shows a QPSK transmission model with the pulse shaping filters.

-MSK stands for minimum shift keying. It is one type of the continuous phase modulation (CPM) schemes (([[http://en.wikipedia.org/wiki/Minimum-shift_keying|Minimum-shift keying]])). In this section, we use "MSK Modulator Baseband" block to modulate the input random binary bits. In other words, the input is either 0 or 1.+MSK stands for minimum shift keying.

 The figure below shows a LTE example according to the specifications developed by the Third Generation Partnership Project (3GPP). It highlights only the downlink physical channel (PDSCH) processing.  In order to obtain the transmitted data, we add a “Signal to Workspace” block on the transmitter side (circled in red). By double clicking the "Model Parameters" block, we can change the model settings such as channel bandwidth, antenna configuration and etc. The figure below shows a LTE example according to the specifications developed by the Third Generation Partnership Project (3GPP).
