Analysis of Code Aided MMSE Receiver for Transceiver Impairments and Multiple Access Interference in CDMA Systems over Rayleigh Fading Channels

Priyanka Kapoor | Amita Soni ^[5]

Abstract: This paper deals with the method to study and improve the interference due to transceiver impairments which occurs due to the some impairments at transmitter and receiver end and other interference such as Multiple access interference sharing of resources like narrow bandwidth and spectral bandwidth in Rayleigh fading channels. Fading is major source of impairement in wireless communications because of the propogation environment. There are various techniques to mitigate these type of interferences; here the CODE AIDED MMSE detector is considered as this technique results in better interference rejection than linear MMSE detector.
