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

Spectrum Analysis of Spreading & Dispreading in WCDMA-3G

How Spreading & Dispreading in WCDMA-3G ? Traditional radio communication systems transmit data using the minimum bandwidth required to carry it as a narrowband signal. CDMA system mix their input data with a fast spreading sequence and transmit a wideband signal. The spreading sequence is independently regenerated at the receiver and mixed with the incoming … Read more
