    摘要: A metric generation scheme for use in OFDM receivers. In a preferred embodiment, an OFDM receiver of the invention includes a dynamic quantizer to compress a series of channel-state information values. Also, a bit de-interleaver is provided to de-interleave a series of symbol-based data inverse to interleaving operations at a transmitter end. The de-interleaved symbol-based data is further compressed by another dynamic quantizer to yield a complex signal according to a constellation scheme. Then a metric generator calculates a bit metric of a zero group and a bit metric of a one group for each received bit in which the constellation is divided into the one group and the zero group for each bit location.

    摘要: The present disclosure provides a method includes forming a multi-fin device. The method includes forming a patterned mask layer on a semiconductor substrate. The patterned mask layer includes a first opening having a first width W1 and a second opening having a second width W2 less than the first width. The patterned mask layer defines a multi-fin device region and an inter-device region, wherein the inter-device region is aligned with the first opening; and the multi-fin device region includes at least one intra-device region being aligned with the second opening. The method further includes forming a material layer on the semiconductor substrate and the patterned mask layer, wherein the material layer substantially fills in the second opening; performing a first etching process self-aligned to remove the material layer within the first opening such that the semiconductor substrate within the first opening is exposed; performing a second etching process to etch the semiconductor substrate within the first opening, forming a first trench in the inter-device region; and thereafter performing a third etching process to remove the material layer in the second opening.
