Abstract: 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.
Abstract translation: 一种用于时分双工(TDD)码分多址(CDMA)系统或使用优先于截断算法(TA)的扩展算法(EA)的任何其他系统的数据估计方法。 EA通过选择适当的扩展矩阵来避免实现错误,并接受使用一块硬件。 EA还消除了每个数据字段的尾部中的多个信号的丢失,并且避免了由于Toeplitz矩阵向循环矩阵的转换而导致的错误。
