Abstract

The demand for high bit rate data transmission in digital data communication. In a multi carrier operation, the problem of interference between carrier spectrums appears. Several modulation techniques for digital transmission have recently been investigated for the purpose of achieving narrow signal spectra with power concentrated within a given bandwidth. QPSK modulation is best suited for digital signal transmission. In this paper, an analytical PSD estimation with periodogram, periodogram with a data window and segmented periodogram are discussed and finally, PSD estimation with non averaged and averaged will be simulated with the help of MATLAB codes. The performance of periodogram like spectral leakage and resolution were also simulated in MATLAB.
