Reverse link pilot integrated with block codes

摘要

A technique for encoding digital communication signals. Data symbols are augmented in pilot symbols inserted at predetermined positions. The pilot augmented sequence is then fed to a deterministic error correction block encoder, such as a turbo product coder, to output a coded sequence. The symbols in the error correction encoded sequence are then rearranged to ensure that the output symbols derived from input pilot symbols are located at regular, predetermined positions. As a result, channel encoding schemes can more easily be used which benefits from power of two length block sizes.

1. A base station comprising:
a processor configured to produce first symbols derived from data bits and parity bits; the processor configured to distribute reference symbols among the first symbols in a predetermined pattern; wherein the reference symbols are spaced by a same number of symbols of a plurality of first symbols; wherein the reference symbols are not adjacent to each other; and a transmitter configured to transmit a wireless signal including the reference symbols distributed among the first symbols.
