Abstract

A device (102) supports error correction. A receiver (120) is configured to receive data over a communications link. A decapsulator (122) is coupled to the receiver and configured to create datagrams. A decoder (124) is coupled to the decapsulator and configured to store the datagrams in a table and to create codewords, the decoder storing the datagrams in table columns to create codewords in table rows. A user interface (126) is coupled to the decoder and configured to render images corresponding with the datagrams on the user interface. Advantages of the invention include efficient signal processing and prolonged battery life in mobile wireless devices.

Description

technical field [0001] The wireless environment presents challenges for high-quality communications. The present invention relates to techniques for improving error correction quality while reducing memory, computational and power consumption requirements in mobile wireless applications. Background technique [0002] Advances in semiconductor fabrication technology and digital system architecture have produced very highly integrated circuits containing millions of transistors along with various other components and interconnections. Integrated circuits resulting from the above developments offer significant computing resources at relatively low cost. In turn, the availability of such integrated circuits has led to an increase in the capabilities and variety of consumer electronics, especially mobile wireless products. A unique aspect of consumer electronics is mobile and portable TV receivers. [0003] Due to the continuously increasing demand for improved reception quali...
