Telecommunications method and system

摘要

A method for encoding data for transmitting over a telecommunications network comprising: embedding at least one control or pilot data block within a plurality of real data blocks in the frequency domain; transforming real data in the real data blocks with control or pilot data in the control or pilot data blocks; and modulating the real data blocks and control or pilot data block with one or more transmission sub-carrier signals.

1. A method for optimising at least one Peak to Average Power Ratio (PAPR) in data for transmission over a telecommunications network in the frequency domain using multiple frequency sub-carriers, the method comprising:
segmenting frequency sub-carriers modulated with data within a data block into a plurality of clusters of frequency sub-carriers; embedding a sub-carrier modulated with control data within each cluster of frequency sub-carriers; modifying the phase of each data modulated sub-carrier using the phase of the corresponding control data modulated sub-carrier to provide a modified data modulated sub-carrier; adding a phase shift to every modified data modulated sub-carrier and adding the same phase shift to every control data modulated sub-carrier within a cluster and determining the PAPR for the added phase shift; varying the phase shift added and determining the PAPR for the varied phase shift; repeating the step of varying the phase shift added and determining the PAPR for each varied phase shift to determine an optimised PAPR phase shift;
applying the optimised PAPR phase shift to the modified data modulated sub-carriers and the control data modulated sub-carrier to form a phase shifted cluster; and transmitting the phase shifted cluster, wherein the phase shifted cluster is decodable without requiring information on the optimised PAPR phase shift.
