he additional path loss as a result of NLoS operation. In clear weather conditions when radio-link SNR is high, the spectral efficiency and through- put are increased by employing higher order QAM constellations such as 256QAM, 1024QAM, or even 4096QAM. In poor weather conditions as SNR degrades, the modulation order can be lowered to 16QAM or QPSK to ensure operational link for high-priority data but at reduced throughput. However, shifting to higher order QAM constellations yields a point of diminishing returns in terms of throughput gained versus added cost, RF transmitter power utilized, required RF signal-chain linearity, and higher dynamic range. With each increase in modulation order, 3-4 dB increase in SNR or transmitter power is needed; however, with each increase in modulation order the throughput only improves by about 10%. Co-channel dual polarization (CCDP) utilizes cross-polarization interference cancelation (XPIC)51 to double the link capacity over the same channel. CCDP-XPIC allows simulta- neous transmission of two separate data streams on the same frequency. Data is transmitted Cross-polarization interference cancelation is an algorithm to suppress mutual interference between two received streams in a polarization-division multiplexing communication system. The cross-polarization inter- ference canceler is a signal processing technique implemented on the demodulated received signals at the baseband level. This technique is typically necessary in polarization-division multiplexing systems where the information to be transmitted is encoded and modulated at the system's symbol rate and upconverted to an RF carrier frequency, generating two (orthogonally polarized) radio streams radiated by a single dual-polarized antenna. A corresponding dual-polarized antenna is located at the remote receiver site and connected to two RF receivers, which down-convert and later combine the radio streams into the baseband signal. 5G Network Architecture Small-cell site ((< ) fiber Satellite VSAT network gateway rout
