Detailed Description

Model the error rate for different modulations.

A packet of interest (e.g., a packet can potentially be received by the MAC) is divided into chunks. Each chunk is related to an start/end receiving event. For each chunk, it calculates the ratio (SINR) between received power of packet of interest and summation of noise and interfering power of all the other incoming packets. Then, it will calculate the success rate of the chunk based on BER of the modulation. The success reception rate of the packet is derived from the success rate of all chunks.

The 802.11b modulations:

• 1 Mbps mode is based on DBPSK. BER is from equation 5.2-69 from John G. Proakis Digitial Communications, 2001 edition
• 2 Mbps model is based on DQPSK. Equation 8 from "Tight bounds and accurate approximations for dqpsk transmission bit error rate", G. Ferrari and G.E. Corazza ELECTRONICS LETTERS, 40(20):1284-1285, September 2004
• 5.5 Mbps and 11 Mbps are based on equations (18) and (17) from "Properties and performance of the ieee 802.11b complementarycode-key signal sets", Michael B. Pursley and Thomas C. Royster. IEEE TRANSACTIONS ON COMMUNICATIONS, 57(2):440-449, February 2009.
