摘要： A digital broadcast system is disclosed. The known data, which is identified by the transmitting/receiving ends, is inserted to a particular place in data region, to which the enhanced data is transmitted, and then transmitted to the receiving end. The receiving end uses the known data when performing modulation and equalization. Therefore, receiving performance of the receiving system can be enhanced in circumstances in which channels significantly vary and there is serious noise. The system initializes a memory of a Trellis encoder at the beginning part of the known data stream, and performs additional encoding, based on block coding for the enhanced data at the transmitting end, using the initialization, thereby increasing its encoding performance.

摘要： The present invention relates to a digital broadcasting system. More particularly, the present invention inserts and outputs pre-defined known data, which are already known by a transmitting system and a receiving system, in a specific place within a data area to which enhanced data are transmitted, and the receiving system uses the known data for a demodulating or equalizing process, thereby enhancing a receiving performance in an environment with frequent channel changes and vulnerable to noise. Also, the present invention performs non-systematic RS encoding on enhanced data including known data. Thereby the present invention may enable a continuously long known data sequence to be inserted and raise a degree of freedom for an insertion place.

摘要： The present invention relates to a method for dynamically allocating the power of a pilot channel according to the load of the forward traffic channel, which can increase the capacity of a CDMA forward link. According to the present invention, the power allocated to a pilot channel is not fixed and is variable dynamically on the basis of the traffic load. The method allocates the power of a pilot channel in consideration of the difference between the loads of the first cell and the second cell. If the load of the first cell is lower than the second cell, then the first cell is enlarged and a portion of the load of the second cell is transferred to the first cell. If the load of the first cell is higher than the load of the second cell, then the first cell is reduced and a portion of the load of the first cell is transferred to the second cell. In this manner, the performance in handoff and the capacity can be improved. In other words, according to the present invention, the power of a pilot channel is allocated dynamically considering the difference between the loads of the first cell and the second cell. The present invention can be adapted to the field of technology for optimizing the design of the wireless network in CDMA system.
摘要翻译：本发明涉及一种用于根据前向业务信道的负载动态分配导频信道的功率的方法，其可以增加CDMA前向链路的容量。根据本发明，分配给导频信道的功率不是固定的，并且可以基于业务负载动态变化。该方法考虑到第一小区和第二小区的负载之间的差异来分配导频信道的功率。如果第一小区的负载低于第二小区，则第一小区被放大，并且第二小区的负载的一部分被传送到第一小区。如果第一小区的负载高于第二小区的负载，则第一小区被减小，并且第一小区的负载的一部分被传送到第二小区。以这种方式，可以提高切换中的性能和容量。换句话说，根据本发明，考虑到第一小区和第二小区的负载之间的差异，动态地分配导频信道的功率。本发明可以适用于CDMA系统中无线网络设计优化的技术领域。
