![]() ![]() ![]() These tables and equations are used to estimate the corrupted packet without any actual modulation or demodulation of packets, resulting in a low fidelity model. The abstracted PHY operates on pre-computed packet error rate (PER) tables and equations. Simulations that tolerate low fidelity at the physical layer can use the abstracted PHY model. Fidelity refers to the degree of exactness with which the PHY is modeled in the simulation. Abstracting the physical layer reduces the time taken for simulation at the cost of fidelity. ![]() However, this example models an abstracted PHY where no waveforms are generated or decoded. In 802.11 MAC and Application Throughput Measurement example, full PHY processing is modeled where waveforms are generated and decoded at the physical layer. The example presents a variation of the system model used in the example 802.11 MAC and Application Throughput Measurement. This example shows how to model an 802.11ax network with abstracted PHY.
