    • Methods and apparatus for processing received signals in a multi-carrier system are disclosed. An exemplary method includes estimating one or more first propagation channel coefficients based on a training sequence in each of one or more first slots received over a first radio channel, equalizing signal samples from one or more second slots received over a second radio channel immediately frequency-adjacent to the first radio channel, using the first propagation channel coefficients, and demodulating user data bits from the equalized signal samples. In some embodiments, the training sequence is located at a fixed position in each of the one or more first slots and user data bits are demodulated from a directly corresponding position in each of the second slots. Improved data rates are thus achieved by constraining radio carriers in a multi-carrier system to frequency-adjacent channels and eliminating training symbols from one of the signals.
    • 公开了一种在多载波系统中处理接收信号的方法和装置。 一种示例性方法包括基于在第一无线电信道上接收的一个或多个第一时隙中的每一个中的训练序列来估计一个或多个第一传播信道系数,来均衡来自在第二无线电信道上接收的一个或多个第二时隙的信号样本, 与第一无线电信道相邻,使用第一传播信道系数,以及从均衡信号样本中解调用户数据比特。 在一些实施例中,训练序列位于一个或多个第一时隙的每一个中的固定位置,并且用户数据位从每个第二时隙中的直接对应位置解调。 因此,通过将多载波系统中的无线电载波限制到频率相邻信道并从一个信号消除训练符号来实现改进的数据速率。

    • The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.
    • 本发明的无线接收机容纳双载波演进EDGE,而不会显着影响现有的接收机架构。 本发明的接收机包括共享本地振荡器和两个图像拒绝下变频器。 本地振荡器在相邻无线电信道的两个载波频率之间产生本地振荡器频率。 接收机在每个相邻无线电信道中接收信号。 在双载波模式中,第一图像拒绝下变频器使用本地振荡器频率来下变频在第一无线电信道中接收的第一信号,同时拒绝在第二无线电信道中接收的第二信号。 第二个图像拒绝下变频器使用本地振荡器频率来下转换第二信号,同时拒绝第一个信号。 在分集模式中,第一和第二图像拒绝下变频器使用本地振荡器频率来下变频在一个无线电信道中接收的信号,同时拒绝在另一个无线电信道中接收的信号。

    • The wireless communication device and corresponding method described herein selectively switches between a single-frequency mode, such as appropriate for an EDGE network, and a multiple-frequency mode, such as appropriate for a multi-carrier EDGE network. Accordingly, a transmitting wireless communication device selectively switches between a single-channel mapping unit, used during the single-frequency mode, and a multi-channel mapping unit, used during the multiple-frequency mode. The multi-channel mapping unit modulates input data to output a modulated data stream for each of multiple adjacent frequency channels that, when combined, produce a multiple-frequency signal with reduced peak-to-average ratio. A receiving wireless communication device selectively switches between a single-channel demodulator, used during the single-frequency mode, and a multi-channel demodulator, used during the multiple-frequency mode.
