COMMUNICATION METHOD, SYSTEM, AND APPARATUS THAT COMBINES ASPECTS OF CYCLIC PREFIX AND ZERO PADDING TECHNIQUES

摘要

The present invention provides communication methods, systems, and apparatuses. Methods are provided in which a second signal for transmission is obtained by halving values of an initial portion (116) and a tail portion (118) of a first signal, and adding zeros following the tail portion (118). Upon or after reception, a third signal (114) is obtained from the received second signal (112) and used in obtaining information. Obtaining each of an initial portion (116) and a tail portion (118) of the third signal (114) includes adding together at least a portion of each of the initial portion (116) and the tail portion (118) of the second signal (112).
