IEEE 802.11b Physical Layer Simulation

This documentation provides comprehensive information about the IEEE 802.11b physical layer simulation program to facilitate your learning process. The simulation implements key physical layer components including Complementary Code Keying (CCK) modulation at 5.5 Mbps and 11 Mbps data rates, Direct Sequence Spread Spectrum (DSSS) with Barker code spreading for 1-2 Mbps transmissions, and channel modeling with Additive White Gaussian Noise (AWGN). The program features configurable parameters for transmitter power, signal-to-noise ratio (SNR), channel characteristics, and packet size variations. The simulation architecture includes modules for frame encapsulation, preamble generation, modulator/demodulator chains, and error rate calculation algorithms. This reliable and effective tool enables detailed analysis of IEEE 802.11b network behavior, performance characteristics under different conditions, and comparative studies of various transmission scenarios. Users can customize experiments through adjustable simulation parameters and predefined test scenarios. For technical implementation, the code structure typically includes main functions for signal generation, channel impairment modeling, receiver processing chains, and performance metric calculations using BER (Bit Error Rate) and PER (Packet Error Rate) analyzers. Should you have any technical inquiries regarding the simulation implementation or parameter configurations, please feel free to seek clarification.
