摘要： A code division multiple access communication system transmits a pilot and traffic signal over a shared spectrum. The pilot and traffic signal have an associated code and are received over the shared spectrum. The received signals are sampled and the samples are delayed to produce a window. A weighted value for each despread pilot code window sample is determined using an adaptive algorithm. Each window sample is despread with a traffic code. Each despread traffic code window sample is weighted according to a weight corresponding to its respective pilot code sample.

摘要： The present invention is for a receiver incorporated into User Equipment (UE) or base stations of a code division multiple access (CDMA) communication system. The UE and base station are in communication with one of the plurality of base stations and receives a communication signal through the receiver. The communication signal is correlated using a delay locked code tracking loop, that estimates and tracks a channel delay. The tracking loop comprises a reference code generator and an interpolator for generating timed signal versions in response to said communication. A timed signal correlator, included in the tracking loop for correlating at least two of the timed signal versions with the code reference signal. The result of the correlation is used for generating an error signal. An automatic power normalization loop (APN), that is responsive to the interpolator, generates a power error signal that normalizes the error signal through a normalization circuit.

摘要： Data is estimated from a received vector comprising a plurality of communications. A received wireless signal is converted to a baseband signal, which is sampled to produce a received vector. Channel responses are estimated for the received communications. The noise variance is estimated. The noise variance is scaled by a scaling factor. Samples are processed using the estimated channel responses and the scaled noise variance to produce a spread data vector. The spread data vector is despread to recover the data of the received wireless signal.

摘要： A method and apparatus for performing uplink transmission in a multiple-input multiple-output (MIMO) single carrier frequency division multiple access (SC-FDMA) system are disclosed. At a wireless transmit/receive unit (WTRU), input data is encoded and parsed into a plurality of data streams. After modulation and Fourier transform, one of transmit beamforming, space time coding (STC) and spatial multiplexing is selectively performed based on channel state information. Symbols are then mapped to subcarriers and transmitted via antennas. The STC may be space frequency block coding (SFBC) or space time block coding (STBC). Per antenna rate control may be performed on each data stream based on the channel state information. At a Node-B, MIMO decoding may be performed based on one of minimum mean square error (MMSE) decoding, MMSE-successive interference cancellation (SIC) decoding and maximum likelihood (ML) decoding. Space time decoding may be performed if STC is performed at the WTRU.
摘要翻译：公开了一种用于在多输入多输出（MIMO）单载波频分多址（SC-FDMA）系统中执行上行链路传输的方法和装置。在无线发射/接收单元（WTRU）处，输入数据被编码并解析成多个数据流。在调制和傅里叶变换之后，基于信道状态信息选择性地执行发射波束形成，空间时间编码（STC）和空间复用之一。然后将符号映射到子载波并经天线发送。 STC可以是空间频率块编码（SFBC）或空间时间块编码（STBC）。可以基于信道状态信息对每个数据流执行每个天线速率控制。在节点B处，可以基于最小均方误差（MMSE）解码，MMSE连续干扰消除（SIC）解码和最大似然（ML）解码）之一进行MIMO解码。如果在WTRU处执行STC，则可以执行空时解码。

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). The present invention resolves SF ambiguity in the downlink of TSM. 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）。本发明解决了TSM下行链路中的SF模糊性。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的性能被保留在其他WTRU的SF模糊度上。

摘要： A code division multiple access communication system transmits a pilot and traffic signal over a shared spectrum. The pilot and traffic signal have an associated code and are received over the shared spectrum. The received signals are sampled and the samples are delayed to produce a window. A weighted value for each despread pilot code window sample is determined using an adaptive algorithm. Each window sample is despread with a traffic code. Each despread traffic code window sample is weighted according to a weight corresponding to its respective pilot code sample.
