摘要： A method of error correction comprises error correction coding processing and interleaving and de-interleaving processings for digital subcoding data (as opposed to main data) in subchannels (as opposed to the main channel) to be transmitted. Apparatus is provided comprising means for performing those processings. The method comprises the steps of dividing digital subcoding data in one PACKET into a plurality of PACKs; adding a first redundant code for error detection or error correction to each of the PACKs; and interleaving the digital subcoding data in each of the PACKs and the first redundant code; whereby the interleaved data is transmitted together with frame sync signals and main data. The data in the subchannels is coded and interleaved and then recorded so that the distances between the data are maximized. Therefore, if errors should occur, the interpolation can be properly done, thereby improving the error correcting ability without requiring complicated error correction circuit or large buffer memory such as those required for the data in the main channel.

摘要： A GPS receiver can periodically obtain range data without degrading the performance such as positioning sensitivity and positioning speed and conserve energy consumption. Supplied with IF data from a frequency conversion section 4, a synchronization hold section (6) acquires synchronization of a carrier frequency and phase synchronization of a C/A code, holds the acquired state, and obtains necessary information such as range data. When range data is obtained, a switch (23) is turned off to stop supplying the power to the synchronization hold section (6). A control section (7) executes a positioning operation using the obtained range data and the like, finds and outputs positioning information indicative of a current position. Thereafter, the switch (23) is turned on to restart the synchronization hold section (6). In this manner, control is provided to repeatedly start and stop the synchronization hold section (6).

摘要： Signals representing navigation messages from four GPS artificial satellites are received by a GPS receiver and supplied to receiving processors of respective channels, which spectrally reverse-spread and demodulate the signals by way of PSK to produce the navigation messages. The navigation messages are then supplied to a CPU that determines the position of the GPS receiver using satellite time and orbit data contained in the navigation messages. The CPU determines whether each channel is synchronized or not based on the level of a spectrally reverse-spread output (correlated output) signal. If a channel is out of synchronism, the CPU effects a synchronization process. After the synchronization process, the CPU obtains time base data equal to or higher than a bit number. To obtain such time base data in a channel after the synchronization process, the CPU uses time base data equal to or higher than a bit number of another channel that has already been synchronized. Since a preamble is not detected to produce time base data equal to or higher than a bit number, the synchronization process can be effected in a short period of time.
摘要翻译：代表来自四个GPS人造卫星的导航信息的信号由GPS接收机接收并提供给相应信道的接收处理器，该处理器通过PSK进行频谱反扩频和解调信号以产生导航消息。然后将导航消息提供给CPU，CPU使用包含在导航消息中的卫星时间和轨道数据来确定GPS接收机的位置。 CPU基于频谱反向扩展输出（相关输出）信号的电平，确定每个通道是否同步。如果一个通道不同步，CPU会产生一个同步过程。在同步处理之后，CPU获得等于或高于位数的时基数据。为了在同步处理之后的通道中获得这样的时基数据，CPU使用等于或高于已经被同步的另一个信道的位数的时基数据。由于没有检测到前同步码以产生等于或高于比特数的时基数据，所以可以在短时间内实现同步处理。
