Uwb Rake Receiver Performance Analysis for Two Different Modulation Techniques
نویسندگان
چکیده
Sistemele de comunicaţii de banda ultralargă (ultra wideband – UWB) se dovedesc a fi sisteme noi şi sigure pentru comunicaţiile fără fir, datorită capacităţii lor de a asigura comunicaţii de putere scăzută, cu rată mare de transmisie pe distanţe scurte, într-un mediu aglomerat în care avem un număr mare de căi multiple de propagare. Vom analiza şi compara performanţele a trei tipuri de receptoare RAKE (RAKE ideal, RAKE selectiv şi RAKE parţial) şi a două tipuri de tehnici de modulaţie TH-PPM şi TH-PAM în acest mediu.

Performance Evaluation of Time Hopping UWB Transmission Using S-Rake Receiver
In this paper, we address a performance evaluation of Time Hopping Ultra-Wideband (TH-UWB) transmission with proposed procedures, based on Pulse Position Modulation (PPM) and considering IEEE 802.15.3a Channel Models (CM1, CM2, CM3, CM4). Moreover, a Selective Rake (S-Rake) receiver is designed to counter the effects of multipath fading occurring in UWB channel Models. The TH-UWB signal detecti...

This paper demonstrates optimum receiver performance in terms of bit error rate (BER) for time hopping pulse position modulation (TH-PPM) ultra wideband (UWB) system in multiple user interference environment for indoor radio communication. Equal gain combining and selective gain combining have been demonstrated in terms of ideal RAKE (ARAKE), selective RAKE (SRAKE) and partial RAKE (PRAKE) rece...

This paper presents an architecture of Multiband Impulse Radio UWB (MB-IR-UWB) system based on Prolate Spheroidal Wave Function (PSWF) by binary time hopping pulse position modulation (TH-PPM) over multipath fading channel. In order to combat multipath fading, Rake receiver using maximal ratio combining (MRC) is applied to this system, which can successfully capture the unique multipath-rich pr...
متن کاملPerformance of Coherent UWB Rake Receivers with Channel Estimators
In this paper, the performance of DS-UWB and THUWB for a single-user link are compared for a data rate of 100 Mbps using the newly proposed, realistic UWB channel model from IEEE P802.15. The performance of suboptimal, fractionally spaced (FS), coherent Rake receivers with a pulse-matched filter is numerically evaluated with two channel estimation algorithms. DS-UWB and TH-UWB with antipodal mo...
متن کاملRange Extension for UWB Communications
UWB shows great promise for use in a number of wireless communications applications, in particular, short range high bit rate networking. However, due to the emissions limits set by the FCC, commercial systems are limited in range for high data rates. To achieve greater range, both simple and advanced techniques need to be investigated. Current designs for UWB (at least those in the open litera...
