摘要
本发明提出一种多用户迭加传输(multiuser superposition transmission，MUST)的方法及使用所述方法的基站。在示例性实施例之一中，本发明提出一种适用于基站的多用户迭加传输的方法。所述方法包括但不限于：决定要被传输的第一比特流(bit stream)；对第一比特流进行编码藉以产生第一编码比特流，其中第一编码比特流中的各符号(symbol)分别具有多个二进制级别(binary levels)；决定第一编码比特流中各个二进制级别的第一编码率，其中第一编码比特流中的至少二个级别具有不同的编码率；以及基于第一编码率附加第一复数冗余位(redundancy bits)。
The disclosure is directed to a multiuser superposition transmission (MUST) method and a transmitter using the method. In one of the exemplary embodiments, the disclosure is directed the multiuser superposition transmission (MUST) method used by a base station. The method would include but is not limited to: determining a first bit stream to be transmitted; encoding the first bit stream to generate an encoded first bit stream which has a plurality of binary levels per symbol; determining a first encoding rate for each of the binary levels of the encoded first bit stream, wherein at least two of the levels of the encoded first bit stream have a different code rate; and attaching a first plurality of redundancy bits based on the first encoding rate.
