ABSTRACT
This chapter discusses typical challenges in military communications applications. It provides an overview of essential transmitter and receiver functionalities in communications applications and their signal processing requirements. The objective of communications is to transfer information from one location to another. The field of communications is incredibly diverse as it spans a wide range of transport media such as spoken languages, the Internet, and cell phones. Most military communications applications that employ wireless radio frequency transport are already employing embedded communications signal processing or are in the process of migrating to embedded com-munications signal processing. Any communications system consists of both a transmitter and a receiver. The forward-error correction coding processes introduce extra information or redundancy into the data stream. Transmitter processing requirements are principally dominated by the data rate at which the communication system operates. There are almost as many ways to build a communications system as there are communications systems.
