求翻译：copy of the last T cp of the useful symbol period, termed cyclic prefix (CP), is added in front of the useful symbol period. A T w part of this CP is used for windowing; a T g part provides a tolerance for symbol time synchronisation errors and resistance to inter-symbol interference (ISI). In addition to the cyclic prefix, a cyclic postfix of length T w is added.是什么意思？ 待解决
