发明名称 métodos e equipamentos para estimar o retardo de tempo e os deslocamentos de frequência em redes de frequência única
摘要 In one method, an uplink signal carrying at least one block of transmitted samples is transmitted, and a distorted copy of the uplink signal is received as a downlink signal. A plurality of blocks of received samples are generated based on the received downlink signal, and a time delay and frequency offset between the uplink and downlink signals are determined based on a correlation between the block of transmitted samples and at least one of the plurality of blocks of received samples.
