A method for verifying interoperability of an implementation of a communication standard includes monitoring a symbol comprising a set of subcarrier symbols in a communication stream, in which some of the subcarrier symbols of the symbol are generated from pilot symbols, transmitted on subcarriers in accordance with the standard. For a given implementation and a given symbol, it is known which subcarriers will be pilot symbols, and what their pilot symbol values will be. A communication stream, generated by an implementation that is interoperable with the standard, will contain expected pilot information. Using the implementation to be verified, a communication stream is generated, containing pilot information. The generated pilot information is compared with the expected pilot information, and interoperability is determined based on the result of the comparing.
