    Abstract: A VSB communication system or transmitter for processing supplemental data packets with MPEG-II data packets includes a VSB supplemental data processor and a VSB transmission system. The VSB supplemental data processor includes a Reed-Solomon coder for coding the supplemental data to be transmitted, a null sequence inserter for inserting a null sequence to an interleaved supplemental data for generating a predefined sequence, a header inserter for inserting an MPEG header to the supplemental data having the null sequence inserted therein, a multiplexer for multiplexing an MPEG data coded with the supplemental data having the MPEG header added thereto in a preset multiplexing ratio and units. The output of the multiplexer is provided to an 8T-VSB transmission system for modulating a data field from the multiplexer and transmitting the modulated data field to a VSB reception system.

    Abstract: A method and an apparatus for improving power efficiency of a User Equipment (UE) by using channel state information between a Node B and the UE and power headroom information of the UE in a mobile communication system. The method includes acquiring power information in relation to transmission powers of UEs; arranging the UEs in a sequence based on the power information; determining, for each UE according to the arranged sequence, whether a first reception power of a Node B exceeds a second reception power; allocating a resource area including partially consecutive sub-carriers to at least one corresponding UE when the first reception power exceeds the second reception power; allocating a resource area including entirely consecutive sub-carriers to at least one corresponding UE when the first reception power does not exceed the second reception power; and transmitting resource allocation information indicating the allocated resource area to the each UE.

    Abstract: A digital VSB transmission system that is able to send supplemental data along with MPEG image/sound data is enclosed. The system initially encodes the supplemental data symbol to generate a parity bit, and it multiplexes the parity bit with a predefined sequence and transmits the multiplexed data to a receiver. The system is compatible with the existing ATSC 8T-VSB receivers that are already on the market. It can have advantages over the other type of VSB transmission systems that transmit only the predefined sequence. In addition, the system according the to the present invention results a improved robustness against ghost and noise signals in a channel compared to systems using only the ½ rate convolutional encoding.
