ZF (Zero-Forcing)

Zero-Forcing (ZF) is a signal processing technique used in wireless communications to reduce interference between multiple signals transmitted simultaneously. It works by applying a mathematical filter that ideally cancels out interference from other signals at the receiver, effectively "forcing" the interference to zero. While this improves signal clarity, it can also amplify noise, especially when signals are closely spaced or weak. ZF is commonly used in multi-antenna systems to enhance data transmission quality but requires careful design to balance interference reduction with noise amplification.
