Wireless System Simulation

Wireless propagation, coverage, multipath, channel characteristics (and relevant mitigation methods, either in e.g. baseband processing or by antenna diversity algorithms) can be accurately modeled by Spark & Roberts and an optimum system design can be developed.

RF System Architecture Design

... a snapshot of some system analyses.

Some typical aspects considered: linearity (block decomposition, pre-distortion, etc.), noise contributions, gain distribution, PLL (noise, settle time, residual modulation), IQ imbalance, ...

PLL design and analysis

Matlab, Mathematica, Cppsim are only part of the tools used to design and analyze PLL circuitry and performance.

Audio CODEC Analysis

These screenshots were part of an audio CODEC evaluation, as well as Packet Loss Concealment algorithm development and analysis.

CODEC Performance Evaluation

This was part of an assignment to evaluate the performance of different audio CODECs in different configurations.
