This four-day course provides participants with an in-depth examination of wireless digital communication design strategies. Topics covered include digital modulation, radiowave propagation characteristics, signal detection methods, BER performance improvement and simulation techniques, DSP techniques, and RF/hardware architectures.
Upon completing the course, the participant will be able to:
- Describe the migration path for modulation and demodulation techniques.
- List and describe signal processing building blocks for wireless systems.
- Explain methods for mitigating wireless channel impairments.
- Perform system simulations ((de)modulation, BER and channel models).
- Predict system performance and evaluate tradeoffs.
- List TDMA and CDMA techniques, and 4G evolution.
- Describe design issues for wireless systems, particularly those issues in which transmit and receive implementation affect system performance.
System designers entering or currently working in the field of wireless digital communication will benefit from this comprehensive overview of practical design techniques. An electrical engineering background (or equivalent practical experience) is required. Attending the course, DSP- Understanding Digital Signal Processing ( Course 27 ), is suggested.
