| Title: | Adaptive modulation for cognitive radios | |
| Author (s): | Sharma, Gaurav, 1982- | |
| Advisor(s): | Kosbar, Kurt Louis | |
| Department/Lab Affiliations: | Telemetry Learning Center | |
| Issue Date: | 2008 | |

| Citation: | Sharma, Gaurav. "Adaptive Modulation for Cognitive Radios." Master's Thesis, Electrical Engineering, University of Missouri-Rolla, 2007. | |
| Abstract: | "This thesis examines the benefits of using adaptive modulation in terms of spectral efficiency and probability of bit error for cognitive radio networks. In channels that fluctuate dynamically over time, systems that are based upon the conventional methods of fixed modulation formats do not perform well. Adaptive modulation provides many parameters that can be adjusted relative to the channel fading, including data rate, transmit power, instantaneous BER, symbol rate, and channel code rate or scheme. In this thesis, a systematic study on the increase in spectral efficiency obtained by optimally varying combinations of the modulation formats for a cognitive radio is provided...Simulations show how adaptively changing the modulation schemes improves the performance of the system by meeting a BER constraint over a range of SNR"--Abstract, p. iii. | |
