Abstract

This paper describes the control language and common data interface for a real-time digital signal processing (DSP) receiver. This receiver decodes TDMA, AMPS or ETACS cellular digital control channels and blank and burst data in real time, and also decodes POCSAG, GOLAY and NEC digital paging traffic, including POCSAG 2400 bits per second. The receiver also serves as a digital signal strength measurement system over the frequency range of 25 MHz to 2000 Mhz. We describe a low level serial interface standard for the DSP receiver, and discuss techniques which allow multiple DSP receivers to be remotely controlled by a single controller. This arrangement of remote receivers can be configured to measure and respond to real-time multiple-channel traffic on cellular and paging channels for market studies, adaptive RF coverage and control, fraud detection and abatement, and law enforcement applications. With a standardized control language,the receiver system described in this paper can be used for a wide range of custom applications for cellular, paging, and personal communications network (PCN) measurement and control, as well. Extensions of this receiver system allow real-time measurements of cellular control traffic of ERMES paging data to timing accuracies of a millisecond.
