Resource Overview
Simulation of a multicarrier OFDM system comprising 8 MATLAB files: capavsgamma.m (capacity vs. gamma analysis), capavsusernum.m (capacity versus user number), chtry.m (channel try/experiment), rheesub.m (Rhee's subcarrier allocation), shenpowerallo.m (Shen's power allocation), tdma_cap_cal.m (TDMA capacity calculation), waterfilling.m (basic waterfilling algorithm), waterfillingPowerAllo.m (enhanced waterfilling power allocation)
Detailed Documentation
This multicarrier OFDM system simulation package contains 8 essential MATLAB files implementing various aspects of OFDM system analysis. The implementation focuses on key OFDM techniques including capacity analysis under different SNR conditions (gamma), user load scenarios, subcarrier allocation methods, and power distribution algorithms.
The files implement sophisticated algorithms such as:
- Waterfilling algorithm for optimal power allocation across subcarriers
- TDMA capacity calculations for time-division multiple access scenarios
- Comparative analysis between different power allocation schemes (Shen's method vs. waterfilling)
- Channel experimentation and subcarrier assignment strategies
Each MATLAB function contains complete implementations with proper parameter handling, result visualization, and performance metrics calculation suitable for academic research and practical OFDM system design.
