Question:
(a) OFDM signals have a higher PAPR that signal carrier signals do. Describe
(i) Why this is so and what is the impact on radio transmission systems?
(ii) How PAPR reduction will be achieved?
(b) Determine the data rates for different Modulation and Coding Schemes and G values for a WiMAX network as per the table below.
The occupied bandwidth considered is 7 MHz and the sampling factor is 8/7.
What will be concluded?
(d) MIMO combined with OFDM/OFDMA is used to achieve higher data rates, in certain circumstances without increasing available bandwidth.
Explain the following aspects in MIMO.
- Spatial multiplexing v/s Spatial diversity - Beamforming - Receive diversity v/s Transmit diversity
