With a total of eight patents to his name, Hatami's work focuses on enhancing communication systems and improving error correction methods.

Latest Patents

Among his latest patents, Hatami has developed methods for timing advance indication and timing relationships indication for non-terrestrial networks. This innovative method enables communication between user equipment (UE) and non-terrestrial networks (NTN). The UE can calculate a timing advance compensation, which may be either differential or full timing advance compensation. An offset value, K, is indicated to the UE, which is utilized for timing relationships.

Another notable patent is the threshold-based min-sum algorithm designed to lower the error floors of quantized low-density parity-check decoders. This modified version of the min-sum algorithm (MSA) effectively enhances the error floor performance of quantized LDPC decoders. The threshold attenuated min-sum algorithm (TAMSA) and threshold offset min-sum algorithm (TOMSA) selectively adjust the check node log-likelihood ratio (LLR) based on predetermined thresholds, allowing for improved performance even without specific knowledge of the objects involved.
