The code represents a WiMAX topology and calculates the subcarrier gain and channel gain to use them later to find the data rate

1. We have two users and 512 subcarriers. The data rate will be different because the subcarrier gain is different between users; we want to calculate the data rate by using this equation

R= _n=1∑^NB log₂(1+SNR)

Where N is the number of subcarrier. Once we get the data rate for each user we want to compare between (by plot) them to show the fairness of data rate.

2. We want to implement an algorithm to achieve a fairness between user1 and user2, the algorithm can do a fairy allocate for the subcarrier between users. After that we want to measure the performance of this system by using a fairness index for instance. In addition, we want to see the effect of this fairness on the data rate

Some considerations

-the power is equal

-Considering downlink

-Considering standard ieee802.16e

-OFDMA

Note: an explanation on the code should be included.
