Abstract

This chapter focuses on wireless communications, including a discussion of the wireless communication channel and how it impacts the data transmission. The propagation models and fading are discussed further. These phenomena might result in the data to be corrupted in transit from source to sink; some mechanisms must be employed to counter the data corruption. Error concealment methods to counter the problem of data corruption are also discussed in this chapter. They are mainly divided into retransmission techniques and forward error correcting codes. Error correcting codes attempt to correct errors at the sink without a need for retransmission. They are more important from the perspective of this writing and are briefly introduced here. However, their applications are discussed in later chapters.
