Using MATLAB $,$ plot on the same graph the outage probability for selection combining $($SC$)$ and maximum ratio combining $($MRC$)$ techniques for a Rayleigh fading channels for $M=1,2,3,4.$ The plot need to be as a function of the ratio of the mean SNR to the threshold SNR $($i$.$e$.,$ the abscissa need to be $\frac{?}{\text{b}\text{a}\text{r}}\frac{}{{}_0})$ from a range of $-10$ dB to $40$ dB $.$ The $M=1$ case is a single antenna to be used for reference purposes. Discuss the results. Compare and discuss the results of the SC and MRC techniques at $0\mathrm{.}1\%$ outage probability level and complete the table below. Use also the semilogy command to make the $y-$axis logarithmic scale.
