| description | Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique
used in the wireless broadband communication systems these days. It is a form of
multicarrier modulation technique with high spectral efficiency, robustness to
channel fading, immunity to impulse interference, uniform average spectral
density, capacity to handle very strong echoes and very less nonlinear distortion
are the properties of the OFDM. One major disadvantage of OFDM is that the
time domain OFDM signal which is the sum of several sinusoids leading to high
peak to average power ratio (PAPR). This work, a technique is proposed in the
literature for reducing the PAPR in OFDM systems selected mapping technique
(SML) for reducing the PAPR in the simulation result shows the PAPR
reduction of OFDM signals. The aim is to come up with an approach for a new
modified selected mapping (SLM) technique. The modified technique has the
inclusion of the idea of sub block partitioning of signals. The comparative
analysis between the conventional SLM scheme and the modified SLM scheme
shows that the modification gives better complementary cumulative distributive
function (CCDF) of the PAPR of transmitted signal. |
