摘要： A channel determination apparatus and method for a broadcast receiver are provided. The method includes estimating, when the broadcast receiver operates in a sleep state over a preset time period, inter-modulation distortion interference of a plurality of channels by scanning the channels, and receiving, when the sleep state is transitioned to an active state, broadcast data on a channel having the least inter-modulation distortion interference. Accordingly, the inter-modulation distortion interference of individual channels is taken into account to select an optimum channel, thereby resulting in improvement of channel determination accuracy.

摘要： A packet decoding method and apparatus of a digital broadcast system is provided for improving decoding performance by reordering blocks to be decoded and adjusting a number of decoding iterations of each block. A packet decoding method of the present invention includes measuring Signal-to-Noise Ratios (SNRs) of individual packets within a slot, determining a decoding order of the packets according to the SNRs, and decoding the packets in the decoding order. The decoding method and apparatus of a digital broadcast system according to the present invention performs decoding on the packets having the highest channel estimation performance first with reduced number of decoding iterations and reallocates the saved number of decoding iterations to remaining packets having relatively low channel estimation performance, thereby improving the decoding performance of the received packets.
摘要翻译：提供了一种数字广播系统的分组解码方法和装置，用于通过重新排序待解码块并调整每个块的解码迭代次数来提高解码性能。本发明的分组解码方法包括测量时隙内的各个分组的信噪比（SNR），根据SNR确定分组的解码顺序，并以解码顺序解码分组。根据本发明的数字广播系统的解码方法和装置首先对具有最低信道估计性能的分组进行解码，并且将经解码迭代次数重新分配给具有较低信道估计性能的剩余分组从而提高接收到的分组的解码性能。
