Latest Patents

One of Ivan's latest patents is a coding scheme for a wireless communication system. This innovation involves coding techniques for a communication system, such as Orthogonal Frequency Division Multiplexing (OFDM), which can transmit data across multiple transmission channels at varying information bit rates based on the channels' achieved Signal-to-Noise Ratio (SNR). The system utilizes a base code combined with common or variable puncturing to achieve different coding rates required by the transmission channels. The information bits for data transmission are encoded with the base code, and the coded bits for each channel are punctured to meet the required coding rate. Additionally, the coded bits may be interleaved to combat fading and remove correlation between coded bits in each modulation symbol before puncturing. The unpunctured coded bits are then grouped into non-binary symbols and mapped to modulation symbols using techniques like Gray mapping. The modulation symbol may also be pre-conditioned prior to transmission.
