摘要

A communication system for communicating low latency data in a fading channel environment using a data structure having data frames modulated on a subcarrier signal and on a commercial radio channel bandwidth. Low latency data is updated relatively rapidly at the low latency data generator. Because of this constant changing of low latency data at the point of generation in the transmitter end, the present invention communicates low latency data from the transmitter end to the receiver end of the communication system with relatively low delay. This communication system encodes and decodes low latency data using a single block encoding/decoding scheme. Such an encoding/decoding scheme introduces relatively less delay during the encoding/decoding processes while ensuring satisfactory data integrity for data communication in a fading channel environment. Using such an encoding/decoding scheme leads to more currently generated low latency data transmission at the transmitter end and in relatively less time for the decoding process with the decoder structure being more simple at the receiver end.
