Communications Blockset 4.3

HIPERLAN/2

This demo models part of HIPERLAN/2 (high-performance radio local area network), European (ETSI) Standard for high-rate wireless LANs. It employs orthogonal frequency division multiplexing (OFDM) operating in the 5 GHz band and offers raw data rates up to 54 Mbps. The model shows transmitter-side coding and modulation for the 16-QAM, 3/4 code rate mode with a corresponding ideal receiver chain and AWGN channel.

Structure of the Demo

The demonstration contains components that model the essential features of the HiperLAN/2 standard. The top row of blocks contains the transmitter components while the bottom row contains the receiver components.

The table below shows which blocks and subsystems correspond to processes from the standard.

The demo also includes the Bernoulli Binary Generator block as a data source, the AWGN Channel block to simulate noise, and the Error Rate Calculation block and Display block to show error statistics.

Results and Displays

To examine the performance of the demo, use the sink blocks that are included in it, listed in the table below.

The Spectrum Scope and the Scatter Plot after OFDM Receiver are visible upon running the demo. The Scatter Plot after normalization is viewed by double-clicking the Transmitted Signal Scatter Plot block.
