Abstract
A description is given of a class of signal structures that are resistant to the effects of narrowband interference based on OFDM signals and error-correcting coding. Algorithms for receiving these signal structures are given using the weighted processing of input implementations in the presence of channel interference under consideration and the criterion of weight windows is given. It is shown that the Kaiser and Dolph–Chebyshev weight windows belong to the class of practically optimal windows. The error-performance characteristics for a number of considered signal constructions formed using a convolutional code with a code rate of 1/2 are given.
