The queuing performance of the cross-layer system with Space-time block code (STBC) over Multi-input-multi-output (MIMO) channel is analyzed. The Adaptive modulation and coding (AMC) in physical layer ...

In any transmission scheme, security against eavesdroppers is of importance. Contrary to classical encryption, security directly at the physical layer can be achieved by applying suited coding and ...

Let's look at each of these in more detail starting with the 8PSK modulation scheme. 8PSK is Enough The EDGE standardization leads to changes in the physical layer. In addition to existing GMSK ...

Of course, this bandwidth trade-off requires modifications in the radio's modulation and coding scheme. Figure 1 illustrates the trade-off between system gain and bandwidth in terms of distance vs.
