Abstract
This paper proposes a low power convolver in channel estimation. It works in the time domain. Ram is used instead of register chains in typical architectures. The power is compared when using different depth of rams. The synthesis results show that the power of the ram based convolver of depth 64 can be reduced to only 57% of that of the register based convolver. And the area can be reduced to 67%.
