摘要： The present disclosure relates to a computer-implemented method for estimating a communication channel response, comprising procedures such as: receiving, via the channel, a signal comprising a plurality of symbols, each comprising a plurality of sub-carriers; determining a pilot sub-carrier response and a pilot sub-carrier metric for one or more pilot sub-carriers; and for one or more non-pilot sub-carriers: i) determining a non-pilot sub-carrier metric; ii) if the non-pilot sub-carrier metric satisfies a criterion, determining a particular component (e.g., real or imaginary) of a non-pilot sub-carrier response as a function of different components of one or more pilot sub-carrier responses; and iii) if the non-pilot sub-carrier metric does not satisfy the criterion, determine the particular component of the non-pilot sub-carrier response as a function of the particular component of one or more pilot sub-carrier responses. Other embodiments include a communication apparatus and a computer-readable medium configurable to perform such procedures.

摘要： Exemplary communication apparatus can comprise a receiver; a computer arrangement; and a non-transitory medium comprising computer-executable instructions that cause the apparatus to: receive a signal comprising a plurality of symbols in a first domain; store a portion of the signal comprising at least one symbol in a buffer; determine a frequency offset parameter relating to the buffered portion; apply a correction signal based on the offset parameter to the buffered portion to generate an at least partially corrected signal in the first domain; and transform the at least partially corrected signal into a second domain. In some embodiments, the first domain is a time domain, the second domain is a frequency domain, and the symbols are OFDM symbols. The corrected signal can be further transformed into a third domain. Further, exemplary methods and computer-readable media can be provided embodying one or more procedures the apparatus is configured to perform.
