Abstract

In a packet-based communication system, a transmitter and a receiver implement low power synchronization techniques. The transmitter transmits a packet that includes a two-part preamble. A first part of the two-part preamble is transmitted at a first reduced bandwidth that is smaller than a second bandwidth of the channel, and at least one of a second part of the two-part preamble and another portion of the packet is transmitted at the second bandwidth of the channel. The receiver includes an interleaved analog-to-digital converter (ADC) including multiple sub-ADCs. The receiver turns on a first subset of the multiple sub-ADCs during an idle listening period, and turns on a second subset of the multiple sub-ADCs upon detection of a completion of the first part of the two-part preamble, wherein the first subset of the multiple sub-ADCs is less than the second subset of the multiple sub-ADCs.
