In this paper we investigate the performance of multi user interference alignment based transmit precoding with pair selection in a MIMO-OFDM based closed loop downlink cellular system.

This paper tries to establish a relationship between the AGC (Automated Gain Control) value and thermal noise level in satellite altimetry.

We beat the bandwidth limitation of low-cost IMDD system achieving high-speed PAM-4 transmission.

It is desirable to generate spatially strongly confined dopant distributions. Such dopant distributions can be mathematically described by the Dirac-delta function.

An Orthogonal Frequency Division Multiple Access (OFDMA) based radio-interface is specified by 3GPP for LTE system.

The optimization of modal gain in InAs/InP quantum-dash based lasers is reported in detail.

This article describes a comparative study of Ti/Au, Ti/Pd/Au, Ti/Pt/Au, Mo/Au, Mo/Pt/Au, and Pd/Mo/Pt/Au Ohmic contacts to both n- and p-In(0.65)Ga(0.35)Sb.

This article describes a comparative study of Ti/Au, Ti/Pd/Au, Ti/Pt/Au, Mo/Au, Mo/Pt/Au, and Pd/Mo/Pt/Au Ohmic contacts to both n- and p-In0.65Ga0.35Sb.

We show that a narrow bandwidth optical filter at the receiver side can greatly improve the receiver sensitivity of a nonreturn-to-zero (NRZ)-duobinary system.

About a 100-fold improvement of the second-harmonic generation in a quantum-cascade laser with integrated optical nonlinearity was obtained by including phase-matching considerations in the design
