CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user’s frequency range . It is used as the access method in many mobile phone standards.
Read moreWhat are the design features of CDMA?
CDMA in cellular systems offers attractive features such as the potential for high spectrum efficiency, soft capacity, soft handover and macro-diversity . This has been claimed and demonstrated in various system design studies, analyses and trials.
Read moreHow do you represent data in CDMA?
CDMA is a spread spectrum technique. Each data bit is spread by a code sequence . This means, energy per bit is also increased.
Read moreWhat is the duration of WCDMA frame?
radio frame structure of WCDMA is shown in Figure 1 [15]. Frame structure has an overall length of 10 ms , comprising 15 time-slots. …
Read moreWhat is voice activity factor in CDMA?
The Voice Activity Factor of 0.4 is considered = -4dB . CDMA has 100% frequency reuse. Use of same frequency in surrounding cells causes some additional interference.
Read moreWhere is CDMA used?
Code Division Multiple Access (CDMA) is a sort of multiplexing that facilitates various signals to occupy a single transmission channel. It optimizes the use of available bandwidth. The technology is commonly used in ultra-high-frequency (UHF) cellular telephone systems , bands ranging between the 800-MHz and 1.9-GHz.
