摘要： A method and apparatus for estimating channel tap delays of multipath components in a CDMA received signal. The search for the tap delays are split into two phases namely, a phase 1 and a phase 2 search. The phase 1 search is a coarse resolution quick search adapted to generate a rough estimate of the location of tap delays. During this phase, the candidate codes are summed and the input signal correlated with the code sum creating an ambiguity in the code associated with the multipath. A finer resolution slower phase 2 search resolves the code ambiguity present in the initial rough estimates of the phase 1 search. Additional phase 2 correlations may be performed to implement a code tracking-loop.

摘要： A novel and useful vehicle integrated communications system that provides a solution to the poor performance experienced at the cell edge in a cellular communications system due to weak signal strength and high interference levels. A core cellular communications platform embedded (integrated) into the vehicle platform utilizes multiple antennas integrated into the body of the vehicle which are coupled to a multi-antenna transceiver; receives electrical power from the vehicle power source eliminating the limitations of hand held device batteries; processes multiple MIMO RF signals taking advantage of antenna diversity, beamforming and spatial multiplexing; executes advanced interference mitigation algorithms; implements adaptive modulation and coding algorithms; and utilizes dynamic channel modeling and estimation to significantly improve performance. The core cellular link functions as a platform for any number of vehicle based applications including a smart vehicle repeater, mobile femtocell, inverted femtocell and vehicle infotainment system.

摘要： A novel and useful apparatus for and method of multicast and broadcast service (MBS) macro-diversity based information processing for use in MBS enabled wireless communication systems. MBS allocations and transmissions from base stations are not coordinated and independent of each other. The characteristics of the MBS signal, such as waveform, modulation, timing and frequency domain, used for transmissions in one or more MBS zones by a base station are uncoordinated and unsynchronized with respect to transmissions in other base stations or MBS zones. They all, however, contain the same information content and relate to the same CID (MCID and/or SA). The MS, using multiple detection techniques, uses time and frequency diversity reception techniques to combine MBS transmissions received from multiple base stations. Base stations and/or the network inform mobile stations of whether or not uncoordinated MBS data transmission is supported on the network via a TLV transmitted during the MBS connection setup process. If supported, mobile stations can receive multiple MBS data signals, combining them to generate a single MBS data output stream.
摘要翻译：一种用于在支持MBS的无线通信系统中使用的组播和广播服务（MBS）基于宏分集的信息处理的新颖有用的装置和方法。来自基站的MBS分配和传输不协调并且彼此独立。用于基站的一个或多个MBS区域中的传输的诸如波形，调制，定时和频域的MBS信号的特性对于其他基站或MBS区域中的传输是不协调的和不同步的。然而，它们都包含相同的信息内容，并且与相同的CID（MCID和/或SA）相关。使用多种检测技术的MS使用时间和频率分集接收技术来组合从多个基站接收的MBS传输。基站和/或网络通过移动台通过在MBS连接建立过程中发送的TLV向网络通知是否支持不协调的MBS数据传输。如果支持，移动台可以接收多个MBS数据信号，组合它们以产生单个MBS数据输出流。

摘要： A novel and useful apparatus for and method of Gaussian Minimum Shift Keying (GMSK) single antenna interference cancellation (SAIC) for use in a digital receiver. An interference mitigation module treats the problem of GMSK SAIC in a blind manner and is operative to compensate for the co-channel interference added in the communications channel which is subject to multipath propagation and fading, receiver filter and any pre-channel estimation filtering. The interference mitigation module takes advantage of the spatial diversity making up multiple branches of the received signal. The branches comprise the in-phase and quadrature elements of the received signal, the sampling phases if over sampling is applied and/or multiple antennas. The invention utilizes the spatial diversity of these multiple representations of the received signal and combines (i.e. collapses) the information in the plurality of branches into a single branch that is input to the equalizer.
