Pulsed ALOHA - a Form of Multiaccess UWB Communications
نویسنده
چکیده
Pulsed ALOHA is a form of impulse Ultra-Wideband communication where a bit is carried with each pulse, rather than using a time spreading code. Pulsed ALOHA and Wideband ALOHA are perfect fits to low energy wide-bandwidth communication. They permit energy-efficient higher data rates. Pulsed ALOHA has some unique advantages in collision avoidance and collision tolerance over Wideband ALOHA, when used with multi-receiver diversity reception. Both systems have substantial advantages in rate, energy efficiency, and simplicity over using spreading codes. A one-dimensional network example is given, which could be a model for a system along auto roadways. Index terms ALOHA, ultra-wideband impulse radio modulation, multiaccess communication, carrier sense multiaccess, antenna arrays, road transportation communication.

متن کاملA controlled multiaccess protocol for packet satellite communication
A controlled multiaccess protocol for packet satellite communication is introduced and analyzed in this paper. This protocol is fully distributed and no on-board processing is required for the satellite. A control parameter f is used to adaptively control the packet transmission rate such that maximum system capacity can be attained and the average delay is always minimized for a given throughp...

متن کاملPerformance evaluation and comparison of different modulation schemes for UWB multiaccess systems
Ultra wideband system performance is analyzed in terms of error probability for different modulation and multiaccess schemes over the AWGN channel. The analysis leads to closed-form expressions of the bit error probability under the hypothesis of chip-synchronous systems, allowing a comparison of different techniques in a possible scenario for UWB applications. The use of convolutional codes to...
متن کاملA Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications
This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...
