Personal Communications System Voice Terminal (PCSVT)

The Warf ighter Information Network (WIN) is an evolving Command, Control Communications, and Computer network composed of communications systems whose roots can be traced back to the commercial sector. The primary WIN charter is to dramatically increase the speed and quantity of information transported throughout the battlespace, while adopting commercial standards to leverage the investment. A crucial link in the WIN communications hierarchy is the Future Digital Radio (FDR), which will provide a high speed digital link as well as an interface between the WIN and users of selected legacy radios. The FDR is the anticipated follow-on to the Near Term Digital Radio (NTDR) which is nearing completion. Therefore, it is essential to determine the degree to which the NTDR's `open' architecture objectives have been met. Nova's proposed program includes a detailed system analysis to answer this crucial question. In addition, Nova will assess the viability of providing PCS voice services over the Wireless LAN data channel. To validate this analysis, Nova's COTS vocoders, spread spectrum transceivers, and reconfigurable DSP cards will be integrated to demonstrate a set of Voice/Data Terminals and Access Points which pass voice and data via a Wireless LAN which includes the NTDR. BENEFITS: The proposed system represents an integration of proven technologies in the areas of low rate vocoders, spread spectrum transceivers, and novel network structures. This combination, once fully reduced to practice, represents a powerful solution for a variety of communications needs which demand distributed voice over a wide area.
