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 ...

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 ...

Abstract: Mobile WiMAX is a broadband wireless access based on OFDM/OFDMA technology which employs Adaptive Modulation and Coding (AMC) scheme to attain higher data rates. In this paper, a selection ...

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.
