In this i attached matlab code for indoor localization using WIFI and FM signal features classified by KNN classifier to predict the fingure print of the building structure.

Aim: do walsh coding with hamming distance.To compare WALSH decoding for synchronous CDMA with decoding using hamming distance. a) System should be supplied with correct/ corrupted version (one/ two bit) of transmitted walsh code(s) b) System should also have table for correct codes(walsh codes) c) System should ab able to deocde the same using hamming distance property. d) Copmare resutls for corrupted code(s) to check the efficacy of WALSH decoding technique (as in above experiment) compared to hamming distance decoding.
