Overview
The Reed Solomon Encoder is fed with an input message of K information symbols, the Encoder appends 2T parity symbols to the input message in order to form the encoded codeword.
The Reed Solomon Decoder receives an (N=K+2T) codeword, and it can locate and correct up to 8 possible symbol errors or up to 14 erasures.
Both the Encoder and the Decoder support any input timing pattern, in the case of the Encoder; the output timing pattern will be the same as the input. In the case of the Decoder; the output timing pattern is fully controlled in order to support any desired pattern by the user.
The Reed Solomon Decoder keeps track of corrected errors. Input codewords with more than 8 errors are regarded as uncorrectable and are flagged.
The Implementation of VK-301 Reed Solomon IP Core targets very low latency, high speed, and low gate count with a simple interface for easy integration on SoC applications.

It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
