摘要： This invention provides a transmission architecture of transmitter which includes a forestage module, a pilot insertion, a scramble selector, and a backstage module. A frequency domain data symbol is transmitted by the forestage module. A pilot signal is inserted in the frequency domain data symbol by the pilot insertion, and a frequency domain pilot symbol is produced. The frequency domain pilot symbol performed a scramble operation and a select operation with certain scramble patterns by the scramble selector, and a requirement symbol is produced. The requirement symbol is converted into the transmitted signal by the backstage module. Because the use of the scramble operation and the select operation from the scramble selector, the transmission architecture of transmitter provided by this invention can both reduce the PAPR and increase the multi-cell diversity gain in an OFDM single frequency network system.

摘要： A method for inter-carrier interference cancellation is provided. A time-domain received signal is detected to obtain information of an inter-symbol interference free region. Multiple cyclic useful symbols are obtained from the time-domain received signal according to the information of the inter-symbol interference free region and a set of multi-step windowing coefficients is generated. Adjusted cyclic useful symbols are obtained by multiplying the cyclic useful symbols by the set of multi-step windowing coefficients, respectively, and then combined in a time domain to obtain a time-domain combination signal. The inter-carrier interference of each of sub-carriers of the time-domain combination signal is centralized on neighboring D sub-carriers. The time-domain combination signal is transformed into a frequency-domain received signal. The frequency-domain received signal and its corresponding channel response matrix are divided into overlapped signal blocks according to D. Successive inter-carrier interference cancellation is performed on each signal block in parallel to obtain estimation data.
