Simpliied Polynomial-expansion Linear Detectors for Ds-cdma Systems

  title={Simpliied Polynomial-expansion Linear Detectors for Ds-cdma Systems},
  author={Dai Lei and Teng Joon Lim},
The multistage linear receiver of 1] was designed to approximate the decorrelat-ing detector and the MMSE detector without calculating the inverse of the cross-correlation matrix R of the spreading codes directly. However, it is complicated by the need to calculate a set of weights using a procedure involving the inverting of a large matrix. In this letter, a modiied structure is proposed to accomplish the same task without the need for computationally-intensive procedures such as matrix… CONTINUE READING
