Latest Patents
One of his latest patents is the "Receiver for an LDPC based TDS-OFDM communication system." This invention involves an LDPC based TDS-OFDM receiver designed to demodulate an LDPC encoded TDS-OFDM modulated RF signal. The system includes a synchronization block, an equalization block, an OFDM demodulation block, and a FEC decoder block. The synchronization block generates a baseband signal from a digitized IF signal and performs correlation of a PN sequence in a signal frame of the received RF signal with a corresponding locally generated PN sequence. This process provides signals for carrier recovery, timing recovery, and parameters for channel estimation. The equalization block is responsible for channel estimation and channel equalization. The OFDM demodulation block performs demodulation on the baseband signal to recover OFDM symbols and converts these symbols to the frequency domain. Finally, the FEC decoder block includes an LDPC decoder that decodes the OFDM symbols based on the LDPC code to generate a digital output signal indicative of the data content of the RF signal.
Another notable patent is the "Distributed switch memory architecture." This invention describes a distributed memory switch system for transmitting packets from source ports to destination ports. It comprises a plurality of ports, including a source port and a destination port, where a packet is transmitted from the source port to the destination port. The system features a memory pool and an interconnection stage that connects the ports to the memory pool, allowing packets to be transmitted efficiently.
