Abstract: Long Term Evolution-Advanced (LTE-A) targets the peak data rates in surplus of 3Gbps for present and next generation wireless communication systems. Turbo coding, the stated channel coding scheme in 3rd Generation Partnership Project (3GPP) LTE standard, is an advanced forward error correction (FEC) coding to achieve higher throughput of advanced Wireless Communication Systems. To support the peak throughputs, parallel turbo decoding procedure has become a necessity and the corresponding VLSI implementation is extremely challenging task to the design engineers. The higher throughput applications require higher parallelism of turbo decoder design; which results in increased hardware complexity, major source of power consumption and silicon area. This paper addresses the design and implementation aspects of different parallel turbo decoders, which meet peak data rates of 3GPP LTE and LTE-Advanced standards, where throughput, power consumption, silicon area and latency are the most decisive cost factors
