摘要： The present invention relates to a transmitting apparatus, a receiving apparatus, a system and a method of re-transmitting data, wherein a signal, which has been transmitted on a first set of original subcarriers, is re-transmitted on a second set of re- transmission subcarriers. A transmission quality information of the original subcarriers and the re-transmission subcarriers is compared and the second set of re-transmission subcarriers is obtained by assigning a re-transmission subcarrier with the highest transmission quality not yet assigned among the second set to an original subcarrier with the lowest transmission quality among the first set.

摘要： A direct current (DC) offset estimation, frequency offset estimation, and compensation system (200), receives data packet (204) with preamble (206). A DC offset estimator (210) and a frequency offset estimator (212) operate concurrently to produce estimates of DC and frequency offsets of the data packet (204), which are determined from a portion of the preamble (206) as it is received. As the data packet (204) is received, a compensator (214) receives the estimates of DC and frequency offsets and compensates the remaining portion of the data packet (204) to produce a DC and frequency compensated data packet (218). Concurrent operation of the DC estimator (210) and the frequency offset estimator (212) advantageously allows more time to produce the estimates of DC and frequency offsets.
摘要翻译：直流（DC）偏移估计，频率偏移估计和补偿系统（200）以前导码（206）接收数据分组（204）。 DC偏移估计器（210）和频率偏移估计器（212）同时操作以产生数据分组（204）的直流和频率偏移的估计，所述估计是从所接收的前导码（206）的一部分确定的。当接收到数据分组（204）时，补偿器（214）接收DC和频率偏移的估计，并补偿数据分组（204）的剩余部分以产生DC和频率补偿的数据分组（218）。 DC估计器（210）和频率偏移估计器（212）的并行操作有利地允许更多的时间来产生DC和频率偏移的估计。
