FORWARD error correction (FEC) is one of the key tools that enabled the explosive growth of the wireless communications industry in the last decade. The basic role of FEC is to provide the users with reliable digital transmission using minimum excess power, bandwidth and complexity. Consequently, FEC substantially contributed to the success of transformation towards the A5 vision (anyone to access anything from anywhere at anytime on any device). Such vision has placed stringent quality of service (QoS) requirements, which require optimal design at all layers of the wireless communications protocol stack to reduce the cost, power consumption and complexity while increasing the capacity, coverage and reliability. Watching high definition television (HDTV) on small-size mobile devices is an example for such extreme QoS requirements because such application requires up to 34 Mbps with packet error rate less than 10−6 [1]–[3]. The problem becomes even more challenging when such mobile devices are used for transmission
For example, video conferencing requires up to 1.92 Mbps and packet error rate of less than 10−4 [2]. In this survey, we consider turbo product codes (TPCs) since they are one of the primary FEC techniques where we summarize the major contributions, present state-of-the-art results, and present the main advantages and disadvantages of TPCs as compared to other well established FEC techniques
Abstract
—Turbo product codes (TPCs) have been integrated in several practical applications, and hence, they have been
considered widely in the literature where the main aim is improving the error performance and/or reducing the computational and implementation complexity. This paper presents a comprehensive survey of the research that focuses on TPCs in terms of encoding, decoding, error performance, and complexity. Moreover, this paper also considers the advantages of integrating TPCs in hybrid automatic repeat request systems where
power optimization becomes very efficient and the complexity can be reduced using the unique properties of TPCs such as error self-detection capabilities. Based on the surveyed literature, the pivotal open research issues in TPCs are presented and discussed
