Latest Patents

Zhiqiang Cui's latest patents include innovative methods for accessing memory during parallel turbo decoding. One of his patents discloses a method for accessing extrinsic information in a turbo decoder. This method involves misaligning operation phases for Forward State Metric Calculators (FSMCs) and Reverse State Metric Calculators (RSMCs) based on whether the current half iteration is even or odd. The first extrinsic information is read from memory into the FSMCs and RSMCs using these misaligned operation phases. The second extrinsic information is then determined using maximum a posteriori probability (MAP) decoders, with each row of the second extrinsic information stored in different memory banks.

Another notable patent describes the architecture for a state metric unit (SMU) in turbo decoding systems. This invention outlines systems, methods, devices, and computer program products for turbo decoding in wireless communication systems. The process involves receiving and demodulating turbo encoded wireless signals, which are then forwarded to a branch metric calculator. The branch metric calculator computes a set of branch metrics for the demodulated signal, which are subsequently compared with previously calculated state metrics to enhance the decoding process.
