摘要： Data is transferred in a wireless communication system, such as a wireless spread spectrum communication system. A plurality of transmitting antennas are provided. Data is encoded to produce a plurality of data streams for each of the plurality of codes. The plurality of data streams are spread with the plurality of spreading codes, and for each transmitting antenna, one of the spread data streams of each code together is combined to produce a spread data vector. Each transmitting antenna transmits its spread data vector. The transmitted spread data vectors are received by each of a plurality of receiving antennas as a received version, and the data is recovered using the received versions.

摘要： A method and apparatus for estimating channelization codes in a wireless transmit/receive unit (WTRU) using blind code detection (BCD). A WTRU receives communication bursts and detects a midamble in the received burst. A candidate code list is generated in accordance with the detected midamble. The candidate code list includes channelization codes intended for both the intended WTRU and other WTRUs. Active channelization codes among the codes in the candidate list are identified, and the identified codes are forwarded to a multi-user detector (MUD). Since the orthogonal variable spreading factor code maintains the orthogonality between codes of different SF, SFs of other WTRUs follow the SF of the intended WTRU. Moreover, since the data for other WTRUs is not used in symbol processing after MUD, the performance of MUD for the intended WTRU is preserved with the SF ambiguity of other WTRUs.
摘要翻译：一种使用盲码检测（BCD）估计无线发射/接收单元（WTRU）中的信道化码的方法和装置。 WTRU接收通信突发并检测接收到的突发中的中间码。根据检测到的中间码产生候选码列表。候选代码列表包括旨在用于预期的WTRU和其他WTRU的信道化代码。识别候选列表中的代码之间的主动信道化代码，并将所识别的代码转发到多用户检测器（MUD）。由于正交可变扩频因子码维持不同SF的码之间的正交性，其他WTRU的SF遵循预期的WTRU的SF。此外，由于在MUD之后的其他WTRU的数据不用于符号处理，所以对于预定的WTRU的MUD的性能由其他WTRU的SF模糊性来保留。

摘要： A method and apparatus for multi-user detection using equalization and successive interference cancellation is provided. A signal is received in a shared spectrum. Samples of the received signal are produced as a received vector. The received vector is segmented into a plurality of vector segments. For each segment, symbols for a plurality of communications are successively determined by determining symbols for a communication and removing a contribution of that communication from the vector segment. The determined symbols are assembled into a data vector for each communication.

摘要： A method of data estimation for a Time Division Duplex (TDD) Code Division Multiple Access (CDMA) system or any other system using an extended algorithm (EA) in preference to a truncated algorithm (TA). The EA avoids implementation errors by choice of proper extended matrices, and accepts the use of one piece of hardware. The EA also obviates loss of multiple signals in the tail part of each data field, and avoids errors due to transformation of a Toeplitz matrix to a circulant matrix.
