Latest Patents
Choi holds a patent titled "Channel error protection implementable across network layers in a communication system." This invention provides a method for channel error protection for a source coded bit stream by utilizing a combination of outer and inner channel coding across different network layers. The outer channel coding is applied in the first network layer, such as the application layer, to create an outer channel coded bit stream with varying levels of error protection. Subsequently, the inner channel coding is implemented in the second network layer, like the physical layer, resulting in a channel coded bit stream. This innovative approach allows for unequal channel error protection for multimedia bit streams in both second generation (2G) and third generation (3G) wireless systems, independent of the physical layer coding infrastructure.
