Features of CDMA

The main features of CDMA system are given below :
  • The CDMA system users share the same frequency either  TDD or FDD can be used.
  • CDMA has a soft capacity limit.
  • In the CDMA system the number of users increases, the system performance decreases.
  • While using in CDMA system near-far problem arises at the receiver end.
  • Multipath fading can be reduced as the signal is spread over a large spectrum.
  • CDMA is an interference limited system.
  • Higher frequency reuse. 
  • CDMA uses co-channel cell.  So the spatial diversity can be used to provide soft handoff.
  • The channel data rates are very high. Hence, the symbol duration is short and less than the channel delay spread.A rake receiver can be used to improve the reception by collecting a time-delayed version of the required signal.
  • CDMA is a protocol implemented in a wireless network device. It is the most famous protocol and implemented in all over world because it offers several advantages.
  • There is not a sheer cutoff in the number of users that it can support unlike TDMA full form or any other traditional cellular device. 
  • TDMA and FDMA both system are suffer from hard hand-off. CDMA system has to eliminate the hard handoff by using a technique logically labeled the soft hand-off. 
  • CDMA has a too much higher user capacity than that of the TDMA disadvantages or FDMA disadvantages system.
  • CDMA is a secures its signals by encoding the user transmission in a unique code.
