GFDM radio transmission using a pseudo circular preamble

摘要

A radio transmission system based on a frequency divisional multiplexing method is described, comprising an improved method for estimating symbol timing offset and frequency timing offset. The receiver estimates the symbol timing offset based of a block of received symbols based on a cyclic prefix and suffix.

1. A method for transmitting digital data using a frequency divisional multiplexing method comprising:
mapping digital payload data to a block of payload symbols, the payload symbols being spread across at least two frequency bands and wherein at least two symbols being conveyed in at least one frequency band; providing a first block of training symbols spread across the at least two frequency bands; appending a suffix to the block of payload symbols, wherein a cross-correlation of the first block of training symbols and a reversed suffix or a cross correlation of the reversed first block of training symbols and the suffix exhibit a pulse like signal upon exact match; and transmitting the first block of training symbols, the block of payload symbols, and the suffix.
