Design Considerations in a Modern Land Mobile Radio System
Modern Land Mobile Radio has the potential for large growth in the near future. Current regulations have set the stage for a required transition to more spectrally efficient technologies. While several organizations are working to ease this transition, there still remain many details and feature sets which the end user must decide amongst and often there is no clear dividing line between these ...
متن کاملPilot-Symbol-Aided 16PSK and 16QAM for Digital Land Mobile Radio Systems
The paper proposes a novel pilot-symbol-aided (PSA) technique for fading compensation of digital signals in the mobile environments. In a PSA system, the data sequence at the transmitter is divided into frames of data. A pilot symbol from a known pseudoradom-symbol sequence is inserted periodically into a frame of data symbol for transmission. In a conventional PSA-receiver, these pilot symbols...
متن کاملDevelopment of Narrow-Band Digital Land Mobile Radio
A narrow-band digital land mobile system has been developed that operates in the frequency bands of 150 and 400MHz, which are commonly used by transportation-related companies, local government, and public-sector organizations— and are therefore very congested. The number of users that can be accommodated in these bands is almost doubled by reducing the channel separation to 6.25 kHz, about hal...

متن کاملEnergy-based Deployment of Mobile Radio Systems
The massive deployment of cellular mobile radio networks claims attentions to their energy efficiency to favor both the eco-sustainability and the economic aspects. In this paper we study the impact of the power consumption in the design of mobile radio networks. We perform the analysis for GSM and LTE systems. The main aim is the analytical evaluation of the optimal cell radius accounting for ...
