There is provided an ultra-light decoder for high speed digital communications based on block codes such as turbo product codes (TPCs). The new decoder can perform soft decision decoding without an algebraic hard decision decoder, which is the core of conventional soft decision decoders. The elimination of algebraic decoder significantly reduces the number of computations required per codeword, consequently, it reduces the decoding delay and processing power. However, reducing the decoding delay would immediately enable increasing the transmission speed, and minimize the need for large buffers at the receiver. Moreover, reducing the complexity and delay would enable using codes with high code rates to increase the system capacity, or use powerful codes with low code rates to reduce the transmission power. Such benefits can be achieved for about 1 dB loss in coding gain. There is also provided a receiver comprising the ultra-light decoder, as well as a decoding process.
