Advantages of CDMA and OFDM
Given below are the Advantages of CDMA and OFDM
Advantages of CDMA
- CDMA is highly efficient and scalable.
- Due to different code words assigned to each user, Interference is decreased.
- Improved security, resistance to interference and jamming, and efficient use of bandwidth.
- Number of users can use the same bandwidth by splitting.
- Uses Fixed frequency spectrum Efficiently.
- CDMA is more protected from hackers.
Advantages of OFDM
- Used to control different parts of the signal in an easy manner.
- Uses Equalization strategy so that there is less interference of the antennas.
- Integrated with MIMO(Multiple Input and Multiple Output) system, so that Multiple samples of same signal is transmitted.
- Used for Avoiding Intercell Interference.
- Simple to use.
- Lost data can be recovered using sufficient channel coding.
Difference Between CDMA and OFDM
Modulation methods are designed to be efficient in transmitting as many bits per hertz as possible. Here the goal is in the given bandwidth these modulation methods have to transmit the data at the highest speed and should minimize the use of spectrum space. Other Modulation methods that use bandwidth greater than the information bandwidth are called wideband modulation techniques. The two widely used wideband Modulation methods are Direct Sequence spread spectrum (DSSS )and orthogonal frequency-division multiplexing (OFDM).CDMA and OFDM both are wide-band wireless communication systems.
