Problems solved by technology

For extremely high data rates (eg, 1728MHz, which has been adopted in the IEEE 802.15.3c standard), it is not practical to operate the high clock frequency
Additionally, power dissipation can be exceptionally high in this case

Abstract

Certain aspects of the present disclosure relate to a method for employing a special format for transmitting data blocks which allows parallel equalizations at a receiver. By applying parallel equalization operations, a clock at the receiver can operate at a fraction of the input signal's data rate, which is more practical in the case of very high data rates while power dissipation is also reduced.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 037,652, filed March 18, 2008, having attorney docket number 082838P1, which is assigned to the present assignee and is hereby incorporated by reference are expressly incorporated herein. technical field [0003] Certain aspects of the disclosure relate generally to wireless communications, and more particularly, to physical layer signal processing in wireless communications systems. Background technique [0004] An ultra-wideband (UWB) physical layer (PHY) may be used for millimeter wave communications (eg, communications with a carrier clock of approximately 60 GHz). Dual-mode UWB PHYs supporting single-carrier and Orthogonal Frequency Division Multiplexing (OFDM) modulation can use a common mode. The common mode is the single carrier mode used by both single carrier devices and OFDM devices for beaconing, network control signaling and basic r...
