additional power is needed under Rayleigh fading to maintain a bit error rate of 10-3? 6. (Rate Adaptation) Browse through the following paper:
Goodput Analysis and Link Adaptation for IEEE 802.11a Wireless LANs, by Daji Qiao, Sunghyun Choi, and
Kang G. Shin
Consider a simple path loss model without shadowing/fading. Use figure 8a from this paper, which relates
throughput to the SNR. Assuming a transmit power of 23dBm, received power at a reference distance of 1m
being -10dBm, and receiver noise of -90dBm, plot the goodput of 802.11a as a function of distance for path loss
exponents 2 and 4. 7. (MATLAB SIMS) Read Prabhu and Shankar, “Simulation Of Flat Fading Using MATLAB For Classroom
Instruction” available online at http://...
