Bandwidth and power efficient OFDM
Orthogonal frequency division multiplexing (OFDM) is an effective modulation technique that is able to support very high rate data transmission under a relatively simple transceiver structure. Due to these features OFDM is adopted as the standard in many wireless applications and being considered as a strong candidate for mobile phone and multimedia communication standards of future generation.
To satisfy the requirements of supporting very high rate and reliable data transmission under limited spectrum availability and constrained transmit power, signal-processing techniques that allow the available signal bandwidth and transmit power to be used more effectively should be applied.
The main factors deteriorating reliability of the OFDM data transmission are nonlinear effects, frequency offset effects and those of deep fading. The aims of the project are:
- Analysis of nonlinear effects, frequency offset effects and those of fading in OFDM-based communication systems ;
- Elaboration of signal-processing algorithms for mitigation of harmful impact of the above factors.
