Abstract :
The complexity of the conventional post Discrete Fourier Transform (DFT) Maximal Ratio Combining may exceed the processing ability of a low-end OFDM receiver. In this paper, we propose a new combining architecture which can reduce the complexity by using cyclic delay combining and orthogonal design simultaneously. Simulation results show that this architecture works well in the OFDM system.
