What is Rake Receiver ? CDMA system uses a signal fast chip rate for spreading spectrum and it has a high time resolution. For this reason, CDMA is able to recognize by decomposing each of the path to reach with the time difference.
Read moreWhat is CDMA how it works?
How CDMA Works. CDMA uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth . This approach allows several people on different cell phones to be “multiplexed” over the same channel to share a bandwidth of frequencies.
Read moreHow does CDMA allow channel reuse?
The IS-95 CDMA and CDMA radio channels use coded channels that are uniquely assigned to each user . This allows many users to operate on the same frequency. This also allows frequencies to be reused in every cell site and sectors within a cell site.
Read moreWhat is CDMA channel bandwidth?
The CDMA channel is nominally 1.23 MHz wide . CDMA networks use a scheme called soft handoff, which minimizes signal breakup as a handset passes from one cell to another. The combination of digital and spread spectrum modes supports several times as many signals per unit of bandwidth as analog modes.
Read moreWhat is WCDMA and GSM and LTE?
WCDMA (Wideband Code Division Multiplexing Access) and GSM are two technologies that are used in mobile telecommunications. The difference between these two is that GSM is a 2G technology and WCDMA is a part of the newer 3G group of technologies .
Read moreWhat is WCDMA vs GSM?
WCDMA is the 3G network that uses radiofrequency to transfer data in the form of calls, messages, or the internet which is also called UMTS. GSM represents 2G networks that were developed way before WCDMA and helps to transfer data through radio technology in the system.
Read moreWhat is a WCDMA network?
WCDMA (Wideband Code Division Multiple Access) UMTS standard for 3G digital mobile networks, using CDMA technology . It is the evolution path for GSM and EDGE to UMTS and offers increased voice capacity and theoretical peak data speeds of up to 2 Mbps.
