Performance Degradation of High Frequency Selective Channel by Implementing Cyclic Delay Diversity CDD in Radio Communication

Cyclic Delay Diversity (CDD) is an effective technique used in radio communication to improve the reliability of a signal. This method is based on the implementation of multiple antennas with specific delays between them in order to spread the signal out in time and reduce interference from other signals. By doing this, more reliable data communication can be achieved at lower power levels than would be possible with only one antenna. It is also useful for Reducing co-channel interference in multiple-input multiple-output (MIMO) communication systems, resulting in an enhanced link budget and higher data rates. Additionally, the use of CDD technique increases the antenna gain of multiple-input single-output (MISO) communication systems, decreasing the required signal strength and increasing its overall efficiency.
