Summer Research Summary

     The first goal of this project is to investigate the properties of a modulation scheme called Complementary Code Keying (CCK), which is a modulation scheme used for 5.5 and 11 Mbps data rates in the 2.4 GHz band.  It is specified in the IEEE Standard 802.11b as an optional modulation format for communication in wireless LANs.  The first property we will determine is the Euclidean distance between the signals in the signal set of CCK modulation.  There are 8 bits represented by each complex code word.  Since a total of 256 code words are possible, we will find the distance between each complex code word and the 255 others.  Since a larger distance between each code word will make it easier to distinguish between code words, the smallest distance between each code word and another will tell us how susceptible the modulation scheme is to noise.  Another property we will investigate is the uniformity of the distance properties of the signal set, which tells us that the distances between one code word and the others are the same as the distances between another code word and the others.

In the second part of the summer, we looked at CCK Modulation in a multi-path channel.
