Chapter Abstract:

This chapter provides a high level summary of the basic signal elements present in a general satellite communications end‐to‐end channel. It also provides an overview of the basic signal processing elements, which are present in virtually all traditional communications systems, including the satellite communications channel. The first three elements, baseband formatting, source combining, and carrier modulation, prepare the signal for eventual introduction to the transmission channel, in our case the ground‐to‐satellite‐to‐ground RF channel. If multiple access (MA) is included in the process it is usually introduced after carrier modulation, shown in the by the dashed line as including components in both ground segments and the satellite itself. The chapter discusses analog signal processing, then focuses on digital signal processing, which comprises the bulk of current satellite communications systems. Phase shift modulations, BPSK and QPSK, are the most widely used in satellite systems.
