    • Methods and apparatus for processing received signals in a multi-carrier system are disclosed. An exemplary method includes estimating (520) one or more first propagation channel coefficients based on a training sequence (330) in each of one or more first slots (300) received over a first radio channel, equalizing (570) signal samples from one or more second slots (380) received over a second radio channel immediately frequency-adjacent to the first radio channel, using the first propagation channel coefficients, and demodulating (572) user data bits from the equalized signal samples. In some embodiments, the training sequence (330) is located at a fixed position in each of the one or more first slots (300) and user data bits are demodulated from a directly corresponding position (350) in each of the second slots (380). 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(300)中的每一个中的训练序列(330)来估计(520)一个或多个第一传播信道系数,使来自一个或多个 通过使用第一传播信道系数立即频率相邻于第一无线电信道的第二无线电信道接收更多的第二时隙(380),以及从均衡的信号样本中解调(572)用户数据比特。 在一些实施例中,训练序列(330)位于一个或多个第一时隙(300)中的每一个中的固定位置,并且用户数据位从每个第二时隙(380)中的直接对应位置(350)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。
