Zero-Forcing Frequency-Domain Equalization for Generalized DMT Transceivers with Insufficient Guard Interval
We propose a zero-forcing frequency domain block equalizer for discrete multitone (DMT) systems with a guard interval of insufficient length. In addition to the insufficient guard interval in the time domain, the equalizer takes advantage of frequency domain redundancy in the form of subcarriers that do not transmit any data. After deriving sufficient conditions for zero-forcing equalization, t...
متن کاملZero-forcing frequency domain equalization for DMT systems with insufficient guard interval
A generalized discrete multitone (GDMT) scheme that not only uses the guard interval but also redundancy in the frequency domain for equalization has been introduced recently [1, 2, 3]. Instead of assigning all redundancy in the time domain it allows to take advantage of unused subcarriers to remove ISI and ICI. In this paper, we calculate the signal-to-noise ratio for each subcarrier for the z...
متن کاملFrequency domain equalization of DMT/OFDM systems with insufficient guard interval
In this paper, we propose a new, generalized approach for equalization of discrete multi-tone (DMT) systems, which not only uses redundancy in the time domain by adding a guard interval, but also takes advantage of existing or intentionally placed redundancy in the frequency domain. For this purpose, we replace the one tap frequency equalizer in the DMT receiver by a block equalizer and derive ...
متن کاملPerfect equalization for DMT systems without guard interval
We propose a new, low-complexity frequency-domain equalizer for discrete multitone (DMT) systems, which, in the absence of a guard interval, utilizes existing redundancy in the frequency domain to completely eliminate intersymbol and interchannel interferences. A perfect reconstruction condition is derived for the noise-free case leading to a sparse equalizer matrix structure. It is furthermore...
متن کاملZero-guard-interval coherent optical OFDM with overlapped frequency-domain CD and PMD equalization.
This paper presents a new channel estimation/equalization algorithm for coherent OFDM (CO-OFDM) digital receivers, which enables the elimination of the cyclic prefix (CP) for OFDM transmission. We term this new system as the zero-guard-interval (ZGI)-CO-OFDM. ZGI-CO-OFDM employs an overlapped frequency-domain equalizer (OFDE) to compensate both chromatic dispersion (CD) and polarization mode di...
