Double Rayleigh Model

Dent Rayleigh model is similar to Jakes but uses Hadamard function in MATLAB to make the oscillators (somewhat) independent and thus provide results that are a little more realistic than the Jakes model.For more details, please read IEEE paper by Wu Z. from 2004 (Electronics Letters, Volume: 40,...

The geometric double-entity model method (GDEM) is proposed to gives far-near degrees between clusters (namely, GE distances), which integrate the absolute distance between nearest sample sets and the dense degrees of border regions of two clusters. GE distances are measured based on the...

This is a code for simulation of BPSK receiver using Direct Sequence Spread Spectrum. The performnace is evaluated in presence of AWGN and Rayleigh fading. Jakes' Model has been used to obtained coefficients for rayleigh fading.
