Similar to most other digital vehicular cellular systems, IS95 uses speech coding at about 9.6 kbit/s .
Read moreHow many channels are there in CDMA reverse channel?
The Reverse CDMA Channel consists of 2 42-1 logical channels . One of these logical channel is permanently and uniquely associated with each mobile station. That logical channel is used by the mobile whenever it passes traffic.
Read moreWhat is CDMA explain in detail?
CDMA (Code-Division Multiple Access) refers to any of several protocols used in second-generation (2G) and third-generation (3G) wireless communications . As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth.
Read moreWhat are the channels used in CDMA?
The Forward CDMA channel is the cell-to-mobile direction of communication or the downlink path. It consists of four types of channels to transmit voice and control data to the mobile. The types of forward link channels are Pilot, Sync, Paging and Traffic channels .
Read moreWhat type of receiver is used in CDMA?
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.
