摘要: This paper proposes a new inter-cell interference cancellation algorithm called subspace projection in order to eliminate the stronger inter-cell interference . This algorithm is designed for the reverse link of time division duplex-code division multiple access systems. The algorithm works by projecting desired users’ signal vector onto the subspace orthogonal to the subspace that interfers the users’ signal. Low-level simulation results show that the scheme eliminates the inter-cell interference efficiently, improves the receiver performance, and increases the system capacity. 9 Refs. In English.
