چکیده

Polynomial cancellation coding (PCC) is a method of mapping data onto the subcarriers of OFDM which results in reduced sensitivity to frequency offset. [1] – [4]. In this paper it is shown that the amplitude statistics for PCC OFDM are different from ordinary OFDM and the statistics are not Gaussian. The results of simulations for OFDM and PCC OFDM are presented. It is shown that the signal statistics of PCC OFDM can be substantially improved by using a form of offset keying in which low index and high index subcarriers have different symbol periods.

Spectral analysis of OFDM signals and its improvement by polynomial cancellation coding

In orthogonal frequency division multiplexing (OFDM) systems, the subcarriers are generated by an inverse discrete Fourier transform (DFT). OFDM has a relatively slow spectral rolloff. In the literature, the spectra of these subcarriers are often represented by a sequence of sinc functions with the same polarity. This does not explain the intercarrier interference (ICI) cancellation properties ...

Frequency Domain Equalization for OFDM systems with mapping of data onto subcarrier pairs and overlapping symbol periods

Description of Polynomial Cancellation Coded OFDM system OFDM is the modulation method chosen for many high-speed digital communication systems. This is despite OFDM having a number of well-known disadvantages that include extreme sensitivity to frequency offset, large out-of-band power, and high peak-to-mean power ratio. One of the often-quoted advantages of OFDM is that by using a cyclic pref...

Pcc-ofdm with Reduced Peak-to-average Power Ratio

Polynomial cancellation coded orthogonal frequency division multiplexing (PCC-OFDM) with overlapping symbol periods is a modulation technique which overcomes many of the disadvantages of OFDM. PCCOFDM is much less sensitive to frequency offset and Doppler spread than OFDM. PCC-OFDM like OFDM has a high peak-to-average power ratio (PAPR). In this paper it is shown that the PAPR can be reduced wi...

This paper investigates the effects of phase noise on the performance of Polynomial Cancellation Coded Orthogonal Frequency Division Multiplexing (PCCOFDM). Phase noise will cause two effects on PCCOFDM, one is a Common Phase Error (CPE) and the other is Interchannel Interference (ICI). CPE is constant for all subcarriers in a symbol so that it can be corrected using existing techniques while t...
