With a total of seven patents to his name, Chavali's work focuses on enhancing the efficiency and reliability of signal detection in complex communication environments.

Latest Patents

Chavali's latest patents include a system and method for detecting spatially multiplexed and space-time block coded MIMO signals. This innovative approach involves performing QR decomposition of the MIMO signal and partitioning a constellation of symbols into subsets using a set partitioning technique. The method determines the a-posteriori probability (APP) of each branch and calculates Log Likelihood Ratios (LLRs) corresponding to the transmitted bits. These LLRs are then utilized in a Viterbi decoder to accurately determine the transmitted bits.

Another notable patent focuses on systems and methods for calculating log-likelihood ratios in a MIMO detector. This method describes how a communication receiver calculates log-likelihood ratios for each bit of subsymbols across spatial streams. By considering effective noise and scaling bit log-likelihood ratios with the signal-to-noise ratio, the method enhances the performance of MIMO detection.
