Collision Communications, Peterborough, N.H., has been assigned a patent (9,825,784) developed by four co-inventors for “reduced dimension time domain channel estimation in a wireless communication network.” The co-inventors are SagarDhakal, Bedford, N.H., Sayak Bose, Nashua, N.H., Joseph Farkas, Nashua, N.H., and Brandon Hombs, Merrimack, N.H. The abstract states: “Methods and systems for obtaining improved joint channel estimates for a multi-user, frequency-multiplexed data transmission such as SC-FDMA or OFDM begins by estimating separate contributions of users (and/or other signal sources) to the received signal based on joint frequency domain channel estimates. A reduced data set is obtained by subtracting contributions of one or more users from the received data, leaving only the estimated contributions of the remaining users, with noise and residual estimation error signal. Time domain joint channel estimation is then performed on the reduced data set, which is feasible because the number of users has been reduced. In exemplary embodiments, the reduced data set includes only one estimated user contribution. This process is repeated to obtain time domain estimates for all of the users.” The patent application was filed on Dec. 5, 2016 (15/369,544).
