摘要： The present invention provides a method for transmitting/receiving a continuous pilot code in a multi-carrier system. The method for transmitting comprises: performing a time-frequency domain two dimensional encoding on an information bit stream to be transmitted; mapping the encoded bit stream to obtain a continuous pilot carrying encoding information; multiplexing a load, a discrete pilot and the mapped continuous pilot carrying the encoding information based on distribution of the load, the discrete pilot and the continuous pilot on a sub-carrier, to generate a frequency domain signal; and performing a frequency-time domain transforming on the generated frequency domain signal, to obtain a time domain sample. The method for receiving comprises: extracting the continuous pilot from an active carrier of a multi-carrier signal; and performing a time-frequency domain decoding on the extracted continuous pilots to obtain the decision of transmitted information bits. The invention ensures reliable transmission of the information without using additional bandwidth resource by carrying information in the continuous pilots using an encoding scheme.

摘要： Advantage is taken of adaptive allocation techniques by intentionally creating multi-user diversity in an otherwise flat fading environment in order to improve system capacity. In one embodiment, multi-path distortion can be resolved to determine subscriber station (SS) diversity gain. Overall network capacity can be increased by allocating channel assignments to SSs within the network based on determined SS diversity gains. In one embodiment, intentional multi-path distortion is produced by transmitting a signal and a time-delayed version of the signal from a base station (BS).
