Abstract

1. Technical Result Increase of communication systems reliability. 2. Essence A method and apparatus for encoding and decoding to facilitate coherent communication. In encoding, reference symbols are inserted into a stream of data symbols 110 to form a reference coded stream of input data symbols 114. Subsequently, the reference coded stream of input data symbols are prepared for transmission over a communication channel by spreading the reference coded stream of input data symbols with a spreading code prior to transmission over the communication channel. In decoding, a received communication signal 120 is despread with a spreading code to derive a stream of reference samples 132 and a stream of data samples 138. The channel response is estimated by utilizing the stream of reference samples 132. An estimated data symbol is detected from the stream of data samples 138 by utilizing the estimated channel response. 3. Field of Application Electric communication equipment. 4 ind. cl., 6 dep. cl., 3 fig.
