Advantages of CDMA Handoff
Advantages of CDMA Handoff It is “soft”, meaning that communication is not interrupted by the handoff. This is sometimes called “make before break.” This means fewer dropped calls for users…

CDMA Handoff Defination,Types and Capacity
CDMA Handoff Defination,Types and Capacity Handoffs The TIA/EIA Interim Standard, Mobile Station – Base Station Compatibility Standard of Dual- Mode Wideband Spread Spectrum Cellular System (TIA/EIA/IS-95), states that a CDMA…
Reverse Link Traffic Channel Physical Layer in CDMA
The CDMA reverse link uses a different coding scheme to transmit data. Unlike the forward link, the reverse link cannot support a pilot channel for synchronous demodulation (since each mobile…
How Forward Link Channel Format in CDMA
The Base Station transmitter signal is, however, the composite of many channels (with a minimum of four). The Pilot channel is unmodulated (Walsh code 0); it consists of only the…
What type of modulation is BPSK?
Binary Phase Shift Keying (BPSK) is a digital modulation scheme that falls under the broader category of phase shift keying (PSK). It is a fundamental modulation technique used in digital…
Why OQPSK is preferred over QPSK?
Offset Quadrature Phase Shift Keying (OQPSK) is a modified version of Quadrature Phase Shift Keying (QPSK) that addresses certain issues associated with traditional QPSK modulation. OQPSK introduces an offset in…
Why QAM is preferred over QPSK?
Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) are both digital modulation schemes, but they differ in how they encode data onto the carrier signal. QAM is often…
What is the speed of CDMA 1x?
The speed of CDMA 1x, often referred to as CDMA2000 1x or simply 1x, represents the data transfer rate in Code Division Multiple Access (CDMA) networks. CDMA 1x is a…
What is the structure of CDMA network?
The structure of a Code Division Multiple Access (CDMA) network is complex, involving various components and layers to facilitate the transmission of voice and data signals in a wireless communication…
What is the technical specification of TD-SCDMA?
Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is a unique 3G mobile communication standard developed in China. It combines time division duplex (TDD) and code division multiple access (CDMA) technologies….
