    • Channel estimation for a wireless Orthogonal Frequency Division Multiplexed (OFDM) link having pilots on at least some carriers in at least some symbols may be implemented by performing first and second channel estimation processes. The first channel estimation process uses only frequency domain interpolation of the pilots to obtain a first candidate channel estimate for the OFDM link, and the second channel estimation process uses both time domain interpolation and frequency domain interpolation of the pilots to obtain a second candidate channel estimate for the OFDM link. One of the first and second candidate channel estimates is selected for processing a communication received via the OFDM link.
    • 可以通过执行第一和第二信道估计过程来实现在至少一些符号中的至少一些载波上具有导频的无线正交频分多路复用(OFDM)链路的信道估计。 第一信道估计处理仅使用导频的频域插值来获得OFDM链路的第一候选信道估计,并且第二信道估计处理使用导频的时域插值和频域插值来获得第二候选信道估计 用于OFDM链路。 选择第一和第二候选信道估计中的一个用于处理经由OFDM链路接收的通信。

    • System and method for transmitting data to a remote communication device to achieve desirable transmit data block size and data rate based on measurements of the communication link quality to the remote device. The method entails selecting an initial transmit data rate and power based on an initial measurement of the link quality, and a default size for the transmit data block. The data block is then transmitted to the remote, and an acknowledgement (ACK) message is received from the remote. If the ACK message indicates that the data block was properly received, the size for the next data block to be transmitted is increased. Otherwise, the size for the next data block may be decreased or remain the same. Additionally, the transmit data rate may be increased if the remote properly receives a defined number of consecutive data blocks, or decreased if the remote does not receive a defined number of consecutive data blocks.
    • 基于对远程设备的通信链路质量的测量,向远程通信设备发送数据以实现期望的发送数据块大小和数据速率的系统和方法。 该方法需要基于链路质量的初始测量以及发送数据块的默认大小来选择初始发送数据速率和功率。 然后将数据块发送到远程,并从远程接收到确认(ACK)消息。 如果ACK消息指示数据块被正确接收,则要发送的下一数据块的大小增加。 否则,下一个数据块的大小可能会降低或保持不变。 另外,如果远程正确地接收到定义数量的连续数据块,则发送数据速率可能会增加,如果远程没有接收到定义数量的连续数据块,则可以减小发送数据速率。

    • Methods and apparatus enable ATSC-M/H mobile devices to conserve power by entering a high power state at a slot reception start time that is after the start of an ATSC M/H slot and entering a low power state at a slot reception stop time before the end of the ATSC M/H slot. Data lost due to the device being in a low power state during the time between the start time of the ATSC M/H slot and the activation time and during the time between the deactivation time and the end of the ATSC M/H slot are recovered using error correction processing. The slot receive and slot reception stop times may be based on the received signal quality. The receiver circuitry may also be deactivated when the entire payload has been received and skip reception of remaining slots.
