A first set of channel estimates is determined for each pilot symbol within the data over a second time interval comprising at least one first time interval, and time-direction interpolation is performed to determine a second set of channel estimates for a number of data portions in a frequency interval using the first set of channel estimates. The frequency interval comprises a data portion comprising a pilot symbol. Frequency-direction interpolation is performed to determine a third set of channel estimates for each first time interval. The time-direction interpolation and the frequency-direction interpolation can be performed in reverse order with the channel estimates generated by the frequency-direction interpolation being used as inputs for time-direction interpolation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for channel estimation","description":"A method for channel estimation includes receiving data at a number of frequency intervals in a frequency band over a number of first time intervals.
