Abstract

We will show how MATLAB and its signal processing capabilities can facilitate the iterative process of analysis, modeling, simulation and implementation of communications systems.

Starting from underlying mathematical principles, we will discuss how to start with a simple communications system composed of just a modem (modulation and demodulation) and an AWGN (additive-white-Gaussian-noise) channel and progressively add components such as convolutional or turbo coding, channel modeling, multi-carrier transmission (such as OFDM) and multi-antenna techniques (such as MIMO) to approach a prototype of a 4G LTE system.

- Highlights of the presentation include:

- Modeling, simulation and visualizing the performance of the communications system in MATLAB

- Using the Communications System Toolbox to incorporate components such as Modulators, Chanel models, Convolution coding/Viterbi Decoder, Turbo Encoder/Decoder, MIMO and OFDM into your mode

- System-level throughput analysis with adaptive modulation based on channel characteristics

- Accelerating the speed of your MATLAB simulation at each step through parallel processing, code generation and using efficient algorithms

- Automatically generating C code from your MATLAB model with MATLAB Coder

- Prototyping and testing your model as a standalone desktop C/C++ application
