Digital communication systems are characterized by having a filter at the transmitter and receiver sides to band limit the transmitted signals and diminish the effects to intersymbol interference (ISI). The optimum ...

In digital communication systems the use of filters that fulfill the first Nyquist criterion (Nyquist-I), guarantees that a sequence of pulses will not be affected by inter-symbol interference (ISI) if the receiver ...

We propose a hybrid filter to reduce the peak-to-average power ratio (PAPR) on the transmitter side in a long-term evolution uplink scheme. The design of the proposed filter is based on two key components: a finite impulse ...

Las actuales tendencias en los sistemas de comunicaciones inalámbricas, nos llevan a dis- eñar sistemas con un eficiente uso del espectro, ya que los requisitos de tasas de transmisión, de manera conservadora, se duplican ...

Due to the constant increase of information traffic in electronics systems, in recent years new technologies have evolved rapid pace. This fact demands the design of new methods of digital communications that allow to ...

The study proposes a constrained least square (CLS) pre-distortion scheme for multiple-input single-output (MISO) multiple access ultra-wideband (UWB) systems. In such a scheme, a simple objective function is defined, which ...

This paper presents an improved decision feedforward equalizer (DFFE) for high speed receivers in the presence of highly dispersive channels. This decision-aided equalizer technique has been recently proposed for multigigabit ...
