The present disclosure presents methods and apparatuses for enhanced received signal processing using signal-based channel impulse response (CIR) estimation. For example, according to an example method presented herein, a user equipment (UE) or a component therein may receive a signal corresponding to a transmitted signal sent by a network entity, wherein the transmitted signal comprises at least a data channel, estimate chip contents of the transmitted signal, based on the received signal including the data channel, to obtain estimated chip contents, and compute an estimated channel impulse response (CIR) based on at least the estimated chip contents. Based on this estimated CIR, the UE may thereafter reprogram a received signal reconstruction filter, perform interference cancellation procedures, and/or adjust one or more equalizer taps. By performing such functions, the UE may exhibit improved communication characteristics and enable a more robust user experience. |

1. A method of enhanced received signal processing, comprising:
receiving a data signal corresponding to a transmitted data signal sent by a network entity, wherein the transmitted data signal comprises at least a data channel; estimating chip contents of the transmitted data signal, based on the received data signal including the data channel, to obtain estimated chip contents; computing a data signal-aided channel impulse response (CIR) estimate based on at least the estimated chip contents; receiving a pilot signal broadcast by the network entity; computing a pilot signal-based CIR estimate based on the received pilot signal; and computing a combined CIR estimate by linearly combining the data signal-aided CIR estimate and the pilot signal-based CIR estimate, wherein the linearly combining comprises weighting the data signal-aided CIR estimate and the pilot signal-based CIR estimate.
