Detailed Description

an implementation of DSSS error rate model

The 802.11b modulations:

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
