What is Beamwidth and Relation between Beamwidth and Gain

What is Beamwidth and Relation between Beamwidth and Gain What is Beamwidth? The beamwidth is also called the half power beamwidth, including horizontal beamwidth and vertical beamwidth. The horizontal beamwidth and vertical beamwidth is the beamwidth between two points where the power is lower 50% (3 dB) than the maximum radiation power. The common horizontal … Read more

How QPSK & BPSK Modulation in WCDMA?

A data-modulation scheme defines how the data bits are mixed with the carrier signal, which is always a sine wave. There are three basic ways to modulate a carrier signal in a digital sense: amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK). In ASK the amplitude of the carrier signal … Read more
