This paper first introduces the MIMO-OFDM (Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing) system model, and then studies several classical channel estimation algorithms: LS(Least Square) algorithm and LMMSE(Liner Minimum Mean-Square Error) algorithms. Finally, based on the Jacobi iterative algorithm for solving linear equations, the original LMMSE algorithm has been improved...
In this paper, a new packet approximation algorithm based on WF2Q+ of TGPS (T-WF2Q+) has been proposed in multicast orthogonal frequency division multiplexing (OFDM) systems. By using Lambda(t) instead of Lambda, the TGPS scheme could preserve the service guarantees provided by WF2Q+ algorithm for enabling to support the OFDM wireless dynamic communication systems. The proposed resource management...
