Polyphase is a common class of pulse compression waveforms in the radar systems. Oppermann code is one of the used codes with polyphone pattern. After compression, this code has little tolerant against Doppler shift in addition to its high side lobe level. This indicates that the use of Oppermann code is an unsuitable scheme to radars applications. This paper shows that the use of amplitude wei...

The slow PIII response of the electroretinogram (ERG) was studied in the isolated, aspartate-treated bullfrog retina. The slow PIII response reflected mainly rod activity in its time course and spectral response curve, and the ratio of the peak amplitude of the fast PIII response to the slow one remained almost constant within a scotopic range when rhodopsin was kept at a constant concentration...

In a single-degree-of-freedom weakly nonlinear oscillator subjected to periodic external excitation, a small-amplitude excitation may produce a relatively large-amplitude response under primary resonance conditions. Jump and hysteresis phenomena that result from saddle-node bifurcations may occur in the steady-state response of the forced nonlinear oscillator. A simple mass-spring-damper vibrat...

In this paper, we propose a simple technique for the reduction of high Peak to Average Power Ratio (PAPR), based on Clipping and Differential Scaling, in Orthogonal FrequencyDivision Multiplexing (OFDM) systems. In this technique, the amplitude of complex OFDM signal is clippedand then scaled in such a way so that the PAPR is reduced without causingmuch degradation in bit error rate (BER). We h...
