摘要： The method and device for analog simultaneous voice and data transmission over an analog channel encodes at a voice signal sampling rate a sampled voice signal including spectral and pitch information. The encoding comprises extracting the spectral and pitch information from the sampled voice signal to produce a residual signal, and converting the residual signal into a sequence of residual vectors at a Baud rate. Also, a bitstream including non voice data and the extracted spectral and pitch information is produced. By means of a modem unit operating at the Baud rate and producing a modulated output carrier wave supplied to the analog channel, a sequence of symbol vectors is produced in response to the sequence of residual vectors and the bitstream, and the output carrier wave is modulated in response to the sequence of symbol vectors. According to the invention, a fractional sampling-rate conversion is conducted on the residual signal by shifting the voice signal sampling rate by a factor M/N, where M and N are the smallest integers that verify, or closely verify, the following equality: (see fig. I) where R is the Baud rate and F is the sampling rate. This fractional sampling-rate conversion involves anti-aliasing filtering of the residual signal. In this manner, the encoding operates at a voice signal sampling rate independent of the modem's Baud rate.

摘要： A system (50, 52, 54) for multi-crew management comprises an enterprise computing system (50), a mobile field unit (52), and wireless communication network (54) which supports terminal control protocol/internet protocol (TCP/IP). The enterprise computing network (50) comprises application programs (80) through which work orders may be assigned and managed, various server machines containing data related to the work orders, a local area network (LAN) connecting the server machines, and a gateway to the TCP/IP wireless network. A mobile field unit (52) comprises a computing device and modem for communicating over the wireless network (54) to the enterprise computing system (50). A mobil field unit (52) and each machine (60, 62, 64, 66) in the enterprise computing system has a unique IP address assigned to it. Accordingly, commands and data can be communicated freely between all machines.
