Apparatus and method for transmitting data and apparatus and method for receiving data

摘要: Provided are an apparatus and method for transmitting data receiving data, in which the transmission of uncompressed over a wireless network can be performed by retransmitting erroneous bit or group bits, if any, each sub-packet including number bits groups having different significance levels. The includes error detection module determines whether plurality portions transmitted packet levels is based on received response packet; data-packet generation generates retransmission one more according to results determination module; communication transmits through channel.
