Abstract: Turbo codes have become an active area of research owing to the fact that they come closest to the Shannon’s limit for codes. This paper presents a comprehensive survey on turbo codes. The paper begins with an introduction of turbo codes followed by its applications and advantages. Subsequently, prominent work in the field is cited in brevity as literature review. The various approaches of the work have been exemplified. Finally a conclusion is presented pertaining to the topic. It is expected that the paper will render useful insights into the functioning and utility of turbo codes.
