Hi, do anybody know how to implement a matlab code for chosing transmit antenna based on channel capacity.

Consider there are 4 transmitting antenna and one receiving antenna. While transmitting data add pilot signal along the data. now consider that at a particular time t, 1st antenna is transmitting the data through a channel, while all the other antennas are transmitting zero power. receiver=transmitted data*channel+noise. Then Compute the channel estimateh1 using lms/mmse and then feedback the result to transmitter. At next time slot send data through second transmitter and other antennas lept silent. compute h2 using lms/mmse and feedback it to transmitter. same way compute h3, h4. then compare h1,h2,h3,h4 or capacity of each channel and maximum value obtained is considered. That is transmission through which antenna is having high capacity is used for transmission. i need to develop this code but i am helpless. please help me if any one know this. Or else just guide me to write matlab code

I need matlab code for noma technology combined with antenna selection and random linear network coding
