摘要： A method, system, and computer-readable medium for detecting an interferer in a wireless communication system are provided. The method includes receiving a signal having P tones, each of the P tones being associated with a frequency, determining a first signal quality of each of the P tones, determining a second signal quality of each of the P tones, and detecting the interferer that occupies the same frequency as one of the P tones based on the respective first signal quality and the respective second signal quality. The first signal quality and second signal quality behave differently when the interferer is present. The detecting the interferer includes determining a discrepancy in the behavior of the first signal quality and the second signal quality.

摘要： 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.
摘要翻译：提供了一种用于通过信道对数字信息进行编码和解码的系统，方法和计算机可读介质。使用类型映射，并且基于将字母上的向量划分为类型并使用编码和解码过程的枚举。类型映射允许任意大小和日期速率灵活编码的信号字母。提供了最佳速率与信噪比之间的权衡，并且可以用作通信产品中可能采用的前向错误控制。
