Per tone equalization for DMT-based systems
An alternative receiver structure is presented for discrete multitone-based systems. The usual structure consisting of a (real) time-domain equalizer in combination with a (complex) 1-tap frequency-domain equalizer (FEQ) per tone, is modified into a structure with a (complex) multitap FEQ per tone. By solving a minimum mean-square-error problem, the signal-to-noise ratio is maximized for each i...
متن کاملPer-tone equalization for MIMO-OFDM systems
This paper focuses on Multiple-Input MultipleOutput (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems, where the MIMO channel order is larger than the length of the Cyclic Prefix (CP). By swapping the filtering operations of the MIMO channel and the Fast Fourier Transform (FFT), it is shown that each tone of a MIMO OFDM system can be viewed as a MIMO Single-Carrier (SC) system. A...

An alternative receiver structure is presented for discrete multitone (DMT)-based systems. The usual structure consisting of a (real) time domain equalizer (TEQ) with a (complex) 1-taps frequency domain equalizer (FEQ) per tone, is modiied into a structure with a (complex) multitaps FEQ per tone. By solving an MMSE problem, the SNR is maximized for each individual tone. This always results in a...

An alternative receiver structure is presented for discrete multitone (DMT)-based systems. The usual structure consisting of a (real) time domain equalizer (TEQ) with a (complex) 1-taps frequency domain equalizer (FEQ) per tone, is modiied into a structure with a (complex) multitaps FEQ per tone. By solving an MMSE problem, the SNR is maximized for each tone separately. This always results in a...
متن کاملBlind, Adaptive, Per Tone Equalization for Multicarrier Receivers
This paper proposes the application of traditional blind, adaptive algorithms to the per tone structure for equalization in multicarrier receivers. It is shown that the per tone structure lends itself more readily than the TEQ structure to the application of the Constant Modulus Algorithm (CMA) and Decision-Directed LMS (DD-LMS). The result is that CMA and DD-LMS type algorithms can be derived ...
