Analysis of Precoding with Kasami sequence for LTEMIMO

Abstract

In wireless communication, obtaining high SNR at the transceiver is challenging work. The uplink and downlink transmission of cellular
communication technologies are affected by self-interference (SI), Multiple Access interference and Inter Carrier Interference (ICI). Good
Auto and cross correlation function make spread sequences of CDMA ,suitable for reducing interference at eNB(Base station) and UE(User
Equipment). In this paper, Kasami sequence is combined at the transmitter with TM2 transmission mode of LTE in frequency domain to
mitigate MAI in Uplink transmission. BER and SNR plots for with and without Kasami sequence for TM2 mode and results are compared.
Kasami sequence precoding is found to be good for reducing interference in Uplink transmission of MIMO-LTE.
