strategies and mutation

Incest prevention, selection strategies and mutation are unnecessary and consequently cancelled (so it is named pseudo genetic algorithm, PGA).②The model of MUD based on PGA is built using Matlab. There are two users in the experiment. Signal spectra of the 12hot cheap prom dresses are spread by a Gold code of which the period is 31. The communication channel is supposed to be Rayleigh multipath fading channel and AWGN channel. To compare the performance of bit error rate, a similar model of MUD based on the TGA is built, too. The simulations work out the plot of BER vs. SNR, which shows that the MUD based on PGA gains a preferable advantage over the sell discount wedding dresses based on plus size wedding dresses on the facet of receive performance.③Performances such as the elitist search speed and computation complexity are studied in an example of searching the maximum solution of an function. As indicated by the simulation results, the speed of elitist search is accelerated greatly and computation complexity is reduced by half. Analysis of variance (ANOVA) shows that the pseudo genetic algorithm has a higher level of consistency. All these results suggested that new wedding dresses based on wedding gowns dresses takes advantages of simpler structures, faster and steadier convergence over the MUD based on TGA.All the work mentioned above come to conclusions that the PGA-MUD, compared to the TGA-MUD, has merits of smaller BER under the same SNR, smaller computing complexity, simpler structure , faster and steadier convergence.
