PAPR
Obtain the CDF plots of PAPR from an OFDM BPSK transmission specified per IEEE 802.11a specification
Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely.
Using a small script, the cumulative distribution of PAPR from each OFDM symbol, modulated by a random BPSK signal is obtained

Signal processing front end for extracting the feature
set is an important stage in any speech recognition
system. The optimum feature set is still not yet
decided. There are many types of features, which are
derived differently and have good impact on the
recognition rate. This paper presents one more
successful technique to extract the feature set a
speech signal, which can be used in speech recognition
systems. Our technique based on the human auditory
system characteristics and relies on the gammachirp
filterbank to emulate asymmetric frequency response
and level dependent frequency response.
