Most real-world signals carry redundant information from one sample (or snapshot) to the next. The focus of this article is on the use of LP in redundancy removal or data compression for coding applications (also known as linear predictive coding (LPC)). The remainder of the article is organized as follows: LP is formulated and the optimal prediction parameters are derived; the computational aspects and algorithms for the implementation of LP are explored; examples and applications of LPC are presented, and finally, variations on LPC used for coding speech signals are discussed.
