IR-UWB Channel Capacity for Analog and Mostly Digital Implementation

TL;DR

This paper compares the channel capacity of IR-UWB systems using analog and mostly digital implementations, analyzing key parameters and their effects on data rates and frequency scaling.

Contribution

It provides a detailed comparison of analog and digital IR-UWB implementations focusing on channel capacity and key system parameters.

Findings

Digital implementation achieves higher data rates.

Analog implementation's capacity is limited by pulse generator capabilities.

Both implementations' behaviors change with increasing operating frequency.

Abstract

The impact of the type of implementation is considered on the IR-UWB channel capacity. This study is lead for analog and mostly digital implementation. Key parameters and theirs impacts on the channel capacity are exposed in each case: data converters for mostly digital implementations and pulse generators capabilities for analog implementations. These two implementations are compared from a data rate point of view. Their behaviors regarding an increase of the operating frequency are also studied
