In this paper we investigate a comprehensive analysis of Long Term Evolution Advanced (LTE) downlink (DL) physical layer performance using Multi Input Multi Output channel (MIMO) based on standard parameters. The work consists firstly in modeling LTE physical downlink shared channel (PDSCH). The developed model is based on an independent functional blocks(More)
In this paper is fully proved the behavior of the Volterra Series through a Memory-Polynomial Model (MPM) excited by QAM Input and implemented in an Radio Frequency Satellite Link (RFSL). Several sequences of 4-, 8-, 16-, 32 and 64-QAM Inputs were introduced to the MPM. The MPM as special truncation of the Volterra Series showed a correct behaviour for each(More)
This paper is focused on a model for the power amplifier considering the memory effects in short terms, this work was developed for periodic signals through Matlab software and was implemented in Simulink. This model for the power amplifier implements a Memory-Polynomial models. Memory-polynomials prove to be both accurate and easy to implement and was(More)
In this paper, an nLDMOS transistor is developed by slight modifications of the base process steps of 0.35µm BiCMOS technology. Extra two masks are used for the formation of the body region (LB-PWELL) and the drift region with slightly added thermal budget and without resorting to high-tilt implants. The proposed device has a breakdown voltage(More)
This paper describes the design and implementation of a memoryless digital predis-tortion (DPD) system for the linearization of power amplifiers. The system prototype predistorter requirements and architecture are implemented over a DSP-FPGA development kit. The design methodology is described in practical blocks and analyzed in detail with special emphasis(More)
