hello guys,

i am trying to code the below SINR equation any clue how to calculate the path gain in the below equation

 

It's clear that it is the ratio between a received power and the corresponding transmitted power.
It depends of antenna gains and link attenuation, that depends of distance, obstructions, etc.

Thanks Zorro for your replay

I agree with regarding the path gain as i defined it in the matlab as Path gain= Transmit power (P) - Path loss- other losses

I am trying to define the SINR for a network has 10 BSs with 3 BSs serving same locations in the above equation as

SINR= (P*(sum of Path gain from 3 BSs))/(P*(Sum of path gain from the remaining 7 BSs)+Noise)

But as per my definition the SINR will be less than 1 !!

Kindly could you help
 

Hi ayham87,

it is necessary to view the context in order to interpret the meaning of the formula.
For example, if it is a CDMA system the raw ratio can be less than 1, but you must consider the coding gain on order to get the SINR at detection.
Regards
