International Classification:

H04W 16/14
H04W 48/16
H04W 72/08
H03F 3/19
H04W 72/04

Abstract:

The disclosure described herein configures a multi-narrowband transceiver for communication within the television white space (TVWS) frequency spectrum using a log periodic filter, wherein the log periodic filter comprises a plurality of filter elements each having a filter frequency increasing periodically in a same frequency increasing factor (K). Each filter of the plurality of filter elements is configured to filter out second harmonics in a defined frequency range. The disclosure determines a TVWS channel for the communication and switches to a filter element of the plurality of filter elements corresponding to the determined TVWS channel. Data is transmitted and/or received over the TVWS channel using the filter element, thereby allowing narrowband communication over the TVWS channel.
