This paper studies the characteristics of an Ultra-Wideband (UWB) communication system employing Impulse Radio techniques and, specifically, the effects of the matched filter of a correlator receiver in the performance of such a system. Such effects are evaluated in terms of the Bit Error Rate (BER) for a Binary Pulse Position Modulation (BPPM) scheme, in an indoor multipath propagation channel...

We propose a PC-based real-time software Digital Video Broadcasting-Terrestrial (DVB-T) receiver, including hardware, driver, and software parts. The total data rate of DVB-T is much greater than that of Digital Audio Broadcasting (DAB). A more efficient signal processing algorithm than our previous software DAB receiver is necessary to improve the speed of the software part of the DVB-T receiv...

A GPS Radio Occultation occurs when a transmitting GPS satellite, setting or rising behind the Earth limb, is viewed by a LEO satellite that carries on board a space-qualified GPS receiver. In this way, it is provided a vertical sounding of the atmosphere exploiting the relative motion between the GPS and the LEO satellites. The technique proved to be particularly precise in retrieving temperat...

Ultra wideband radio (UWB) is a new wireless technology that uses narrow pulses to transmit information. Implementing an “all-digital” UWB receiver has numerous potential benefits ranging from low-cost and ease-of-design to flexibility. Digitizing an RF signal near the antenna, however, introduces its own set of challenges and has traditionally been considered infeasible. A high-speed, high-res...

A software radio is a radio whose channel modulation waveforms are defined in software. A software radio receiver is an embedded platform that can support different communication standards. All the base-band processing is performed on a DSP. On the receiver side, the base-band processing encompasses matched filtering of the incoming data, frame synchronization, frequency offset and phase offset...

I. INTROEDUCTION The CR wireless network is intended as an advanced technology integration environment with a motivation on making adaptive, spectrum efficient systems with emerging programmable radios.Wireless communication phenomena are mainly due to scattering of electromagnetic waves from surfaces or diffraction over and around buildings[1]. The communication channels are required to design...

Application Note 2 This application note is written for people who need an understanding of Multiple Input Multiple Output (MIMO) radio operation as it applies to Long Term Evolution (LTE). MIMO (otherwise known as spatial multiplexing) is one of several multiple antenna techniques that are being implemented in LTE; however, this application note will primarily focus on MIMO implementations. In...

We present an open source LTE receiver framework. Using GNU Radio‘s block-based signal processing capabilities, various LTE baseband specific functionality has been implemented in dedicated easily reconfigurable blocks. These can be used to decode and analyze arbitrary channels in the LTE downlink signal. As an example we decode the Master Information Block (MIB) transmitted on the Broadcast Ch...

This paper presents analysis of a digital Ultrawideband (UWB) radio receiver operating in the 3.1 GHz to 10.6 GHz band. Analog to digital converter (ADC) bit precision is analyzed on two types of UWB signals OFDM UWB and pulsed UWB all in the presence of Additive White Gaussian Noise (AWGN) and a narrowband interferer in the channel. This paper shows how probability of error and the bit resolut...
