/**
* \brief an implementation of DSSS error rate model
* \ingroup wifi
*
* 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.
*
* This model is designed to run with highest accuracy using the Gnu
* Scientific Library (GSL), but if GSL is not installed on the platform,
* will fall back to (slightly less accurate) Matlab-derived models for
* the CCK modulation types.
*
* More detailed description and validation can be found in
* http://www.nsnam.org/~pei/80211b.pdf
