The present disclosure provides a method, apparatus, and system for increasing data rates and improving robustness in a wireless communication system. The method comprises identifying a set of guard tones for wireless Orthogonal Frequency Division Multiplexing (OFDM) signals, encoding data for OFDM transmission, identifying a preferred puncture pattern to puncture the encoded data, puncturing the encoded data with the preferred puncture pattern, and transmitting the punctured encoded data, wherein a portion of the punctured encoded data is transmitted on a portion of the set of guard tones.

Method, apparatus and system for using guard tones in OFDM systems for increasing data rates and improving robustness

A system, method and computer-readable medium for encoding and decoding digital information over a channel is provided. Type Mapping is employed and is based on the partitioning of vectors over an alphabet into 'types' and using enumeration for the encoding and decoding process. Type mapping allows for signal alphabets of arbitrary size and date rate flexible coding. Tradeoffs between optimal rate versus Signal to Noise Ratio are provided and works as a compliment to the Forward Error Control that may be employed in communications products.
