246Rice type fading generator class.

248<dl class="author" compact><dt><b>Author:</b></dt><dd>Tony Ottosson, Adam Piatyszek and Zbigniew Dlugaszewski</dd></dl>
249A Rice generator is a generator of the form:<p>
250<p class="formulaDsp">
251<img class="formulaDsp" alt="\[ \tilde \mu_i(t) = \sum_{n=1}^{N_i} c_{i,n} \cos(2\pi f_{i,n} t + \theta_{i,n}) \]" src="form_220.png">
252<p>
253<p>
254Here <img class="formulaInl" alt="$ c_{i,n} $" src="form_221.png">, <img class="formulaInl" alt="$ f_{i,n} $" src="form_222.png">, and <img class="formulaInl" alt="$ \theta_{i,n} $" src="form_223.png"> are the Doppler coefficients, discrete Doppler frequencies, and Doppler phases, respectively. Rice showed that a generator of this form can perfectly model a Gaussian process when <img class="formulaInl" alt="$ N_i \rightarrow \infty $" src="form_224.png">. When generating a fading pattern we need a complex-valued generator<p>
255<p class="formulaDsp">
256<img class="formulaDsp" alt="\[ \tilde \mu(t) = \tilde \mu_1(t) + j \tilde \mu_2(t) \]" src="form_225.png">
257<p>
258<p>
259Parameters that define the generator are the normalized Doppler and the doppler spectrum. Possible values of the Doppler spectrum are:<ul>
260<li><em>Jakes, J, Classic, C</em>: The classical Jakes spectrum shape. This method can be also used for modelling LOS paths, by setting the LOS relative power (Rice factor) and LOS Doppler parameters.</li><li><em>GaussI, GI, Gauss1, G1</em></li><li><em>GaussII, GII, Gauss2, G2</em></li></ul>
261<p>
262Furthermore also the number of sine waves, <img class="formulaInl" alt="$ N_i $" src="form_226.png"> and method used to calculate the parameters <img class="formulaInl" alt="$ c_{i,n} $" src="form_221.png">, <img class="formulaInl" alt="$ f_{i,n} $" src="form_222.png">, and <img class="formulaInl" alt="$ \theta_{i,n} $" src="form_223.png"> can be specified. For now the only method defined for calculating the parameters is the Method of Exact Doppler Spread (MEDS). See [Pat02] for more details.<p>
