    117117===== Signal-to-Noise Ratio (SNR)  =====
    118118There are 2 methods to approximate the SNR:
    119 * '''Method 1:'''  Estimate the noise power by measuring the received signal power when transmitter is turned off.
    120 * '''Method 2:''' Estimate the noise power by calculating the received signal variance.
     119* `Method 1`  Estimate the noise power by measuring the received signal power when transmitter is turned off.
     120* `Method 2` Estimate the noise power by calculating the received signal variance.
