摘要： An outer encoder and an inner encoder encode subsets of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. The use of a combiner at an outer decoder enables better outer decoding of symbols.
摘要翻译：外部编码器和内部编码器对要发送的信息的子集进行编码，以通过增加冗余来改善保护。冗余允许从小于完整编码的信息块解码信息。在外部解码器上使用组合器能够更好地对符号进行外部解码。

摘要： Techniques for selectively combining multiple transmissions to recover a message comprised of multiple frames. Initially, each transmission is separately processed to recover the message. If the message cannot be recovered error-free from any single transmission, then portions of multiple transmissions are selectively combined to recover the message. Erased frames in a message recovered from a primary transmission (e.g., the one with the best pilot Ec/I0) and good frames from other transmissions are determined (e.g., based on the frame-level CRC). One or more combined messages are then formed, each including a different set of good frames substituting for the erased frames. If a good frame cannot be derived from any single transmission for a given erased frame, then symbols from multiple transmissions may be combined to derive the good frame. Each combined message is checked (e.g., based on the message-level CRC) to determine whether it is good or erased.

摘要： In a communication system, a method and an accompanying apparatus determine a number of available fingers (110A-N) in a receiver (100). A controller (121) adjusts a threshold based on the determined number of the available fingers (110). The adjusted threshold may be one of, or any combination of, a pilot signal search threshold, a lock/unlock threshold, and a combine/un-combine threshold. The number of available fingers (110) may change after the threshold is adjusted.
