| Summary: | Long Term Evolution (LTE) system has higher
PAPR value at OFDM Downlink. The 3GPP standard stated that
PAPR of LTE OFDM is 12dB. There are various interference
management methods have been proposed to improve PAPR
performance and most known methods are clipping and filtering.
In this work, we proposed DSSS in LTE link-level system. The
DSSS is added before Modulator at LTE Transmitter and after
Modulator at LTE Receiver. The proposed LTE link-level system
is investigated on PAPR and BER performance. The results gave
8.333% of PAPR improvement compare to LTE original and
BER performance has robustness against errors. |
