What is the relationship between power or field strength and the transmission matrix?

Recommended Posts

Tvv is the transmission coefficient in case of both Tx and Rx with vertical polarization.

In the current ProMan version the Rx antenna polarization cannot be defined. For the result maps (of Rx power, pathloss, ...) so far the theta (V pol) and phi (H pol) contributions are always superposed. The received contributions in both V and H are superposed for the Rx power shown in the result map.

For Tx polarization V the total received power given in the result map includes T_vv and Tvh (as mentioned above the received contributions in both V and H are superposed in ProMan so far). This means for Tx with V pol:

Rx_power_V[dBm] = Tx_power[dBm] -  20*log10(T_vv)

Rx_power_H[dBm] = Tx_power[dBm] -  20*log10(T_vh)

and the Rx power shown in the result map is the sum of both (same for the pathloss).

 

Please note that the transmission matrix does not include the Tx antenna gain but describes the properties of the radio channel.
