Sentence examples for widely linear equalizer from inspiring English sources

A widely linear equalizer for SC-FDE systems was proposed in[14].

The paper by M. Lipardi et al. derives optimum and suboptimum techniques for constellation design assuming a widely linear equalizer at the receiver.

This way, the widely linear equalizer A can be expressed as A = C tt - 1 C ts (17) = A 1 A 2 (18).

This happens because the stronger code ratios help compensate some of the performance advantage which comes with the usage of the widely linear equalizer.

For the special case of real constellations, we consider a frequency domain widely linear equalizer which jointly filters the complex-valued received signal and its complex-conjugated and frequency reversed copy in frequency domain (see Figure 2).

It is possible to see that the performance advantage between the widely linear equalizer and the strictly linear one in the case where a time-domain DFE is not used increases when the constellation size grows.

Thus, the coefficients of the Tomlinson-Harashima precoder d ~ ′ = d ~ are given by (29), and the widely linear MMSE equalizer B′ = B is given by (23).

For real-valued data transmission (e.g., binary phase-shift keying (BPSK) or amplitude-shift keying (ASK)), widely linear (WL) equalizers which jointly filter the received signal and its complex-conjugate [33] are known to outperform conventional receivers.

Figure 2 A SC-FDE system employing widely linear MMSE equalization and a decision-feedback equalizer.

In this paper, we propose widely linear MMSE Tomlinson-Harashima precoders and equalizers (including a decision-feedback one) for SC-FDE systems (Section 2).

Due to the fact that widely linear processing is employed in the equalizer, the estimated symbols z ~ at the output of the receiver will be purely real.
