A method and apparatus for transmitting an input data signal over an information channel. The input data signal comprises a sequence of data blocks. A puncture coded signal is generated for each data block in the sequence of data blocks. The total number of bits in the puncture coded signal is equal to the number of bits in a particular data block plus additional error correcting bits used to perform error correction at a receiver. The number of error correcting bits is adaptively adjusted for each data block in response to a channel quality measure for the information channel.

Method and apparatus for adaptively coding a data signal

A method and apparatus for reducing channel distortion in a broadband, wireless network comprising a residential communications gateway that accepts all incoming communications signals and securely broadcasts those signals throughout a residence. In one embodiment, the gateway comprises a space time block encoder to reduce the effects of multipath and at least one error correction encoder to provide error correction. The space time block encoder generates at least two space time block coded signals that are transmitted via the wireless network. Each space time block coded signal is transmitted using a different antenna.
