Abstract: Methods, apparatuses, and systems for packet detection in a point-to-point wireless communication network is disclosed. One method includes receiving, by a receiving node, a plurality of packets, adjusting, by an adjustable gain amplifier of the receiving node, a power level of the received plurality of packets, controlling, by a gain control module, a gain of the adjustable gain amplifier, thereby controlling the power level of the received plurality of packets, monitoring the controlled gain of the gain control module over a period of time, identifying a timing of reception of interfering packets based on the monitoring of the controlled gain of the gain control module over the period of time, and adjustably controlling, by the gain control module, the gain of the adjustable gain amplifier based on the identified timing of reception of the interfering packets.

Abstract: Apparatuses, methods, and systems of assigning codes are disclosed. One method includes selecting a plurality of available codes, grouping links of a wireless network into a plurality of groups based on connectivity of the links between sectors of the wireless network, characterizing interference between at least one link of a first group of the plurality of groups and at least one link of a second group of the plurality of groups, and assigning at least one code of the plurality of available codes to the first group and at least one other code of the plurality of available codes to the second group based on the characterizing of the interference.

Abstract: Methods, apparatuses, and systems for transmitting information between nodes in a point-to-point wireless communication network is disclosed. One method includes constructing, by a sector of a transmitting node, a packet including data that is to be transmitted to a receiving node in the wireless network, wherein the constructed packet includes a short training field, a channel estimation field, a header field, and a data payload, and transmitting by the sector of the transmitting node, a jamming code before the short training field of the constructed packet, thereby reducing a likelihood that the receiving node will decode a different short training field of an interfering packet before the receiving node decodes the short training field of the constructed packet.

Abstract: Apparatuses, methods, and systems of mitigating packet interference are disclosed. One method includes receiving, by a sector, data to be transmitted over a specific wireless link of a wireless network, configuring a packet for transmission over the specific wireless link, wherein the packet includes a preamble, and the data, and transmitting, by the sector, the configured packet over the specific wireless link. Configuring the packet includes identifying a reference sequence based on the specific wireless link, and inserting the reference sequence into at least a portion of the preamble.
