In wireless communication channel modeling, capacity is calculated based on computed H matrix and SNR value.
H matrix is calculated through a different models - COST..WINNER..etc.
I am wondering how to calculate SNR at different locations of UE In a cell?
many papers assume a certain SNR before capacity calculation.
How one can calculate SNR in an urban macro environment in presence of scatterers with different BS-UE positions in distance and angle?
I am looking for SNR calculation throughout a cell for MIMO wireless channel using directive antennas.
Thanks Sumit Kushwaha for your response.
For simulation purpose how to calculate received power in NLOS scenario with signal arriving at UE through multiple paths...

Thank you for your response and informing me that the H matrix would govern the SNR of each spatial channel.
Kindly comment on the following thought process..
As received signal is represented as Y = Hx+n
then here the SNR could be the ratio of (Hx) and (n) ?
can we also use the usual SNR formula [: SNR = Transmit power - pathloss(PL)+Ant. Gain-Noise(-174dB/Hz) ] somehow?
Thanks.
Dear Laxmikant Minz ,
The colleagues above gave satisfactory answer. The ultimate answer of your question is to make survey test at all intended points where one one can measure directly the recieved signal strength. This means one has to determine the spatial distribution of the received signal at the coverage area.
May be the best way is to determine such distribution empirically.
But this may be very tedious.
The other solution is to use use models of large scale fading and small scale fading to obtain statistical channel models.
The last possible solution is to make an electromagnetic solution for the signals emitted from the antennas in the real propagation space with districted scatters.
Best wishes
