Although multicarrier modulation techniques are inherently more resistant to impulse noise than single carrier systems, impulse noise can still be a significant problem in many applications including digital television. A number of impulse noise mitigation algorithms are investigated. These use non linear processing on the digital input signals to limit the… (More)

This paper investigates the effects of phase noise on the performance of Orthogonal Frequency Division Multiplexing (OFDM) systems using an Intercarrier Interference (ICI) cancellation scheme. In this case, the Common Phase Error (CPE) and ICI caused by phase noise depend on the overall spectrum of each weighted group of subcarriers rather than on the… (More)

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… (More)

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… (More)

This paper presents a technique for frequency offset estimation for polynomial cancellation coded orthogonal frequency division multiplexing with symbols overlapped in the time domain (overlap PCC-OFDM) in the presence of phase noise. The frequency offset estimator is designed based on the subcarrier pair imbalance (SPI) caused by frequency offset. The… (More)

This paper presents a new algorithm for frequency offset estimation for Polynomial Cancellation Coded Orthogonal Frequency Division Multiplexing with symbols overlapped in the time domain (Overlap PCC-OFDM). The algorithm exploits the Subcarrier Pair Imbalance (SPI) caused by frequency offset. The estimation is performed in the frequency domain. No training… (More)

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… (More)

In this paper we introduce a new method of carrier frequency offset estimation for Orthogonal Frequency Division Multiplexing (OFDM) communication systems. The method uses one or more pairs of adjacent subcarriers within an OFDM symbol. The pairs of subcarriers are modulated with equal amplitude and opposite polarity. In the absence of frequency offset, the… (More)

The Multiple-Input Multiple-Output (MIMO) – Orthogonal Frequency Division Multiplexing (OFDM) technology significantly provides high transmission rate and robustness against multi-path fading and other channel impairments. Mostly, MIMO-OFDM system is analyzed only in presence of additive white Gaussian noise (AWGN) only, but in practice, in many actual… (More)
