What is interference averaging in CDMA?

Interference averaging in Code Division Multiple Access (CDMA) refers to the technique of mitigating the impact of interference among multiple users sharing the same frequency band. By spreading the signals of each user across a wide bandwidth using unique spreading codes, CDMA allows the receiver to focus on the intended signal while averaging out the interference from other users. This process enhances the overall signal quality and capacity of the system, enabling more users to communicate simultaneously with reduced degradation in performance.
