Abstract: The present disclosure includes systems and techniques relating to wireless devices. A described technique includes generating respective frequency segments of a composite signal which are contiguous in a frequency domain, each of the respective frequency segments being based on a segment bandwidth; applying respective cyclic shift delay (CSD) phase shifts to the respective frequency segments to produce respective output signals; and transmitting the composite signal by transmitting signals that are based on the respective output signals. The respective CSD phase shifts, including first and second CSD phase shifts, are equivalent to third CSD phase shifts that correspond to a contiguous non-composite signal having a single frequency segment. A bandwidth of the single frequency segment is at least twice the segment bandwidth. The respective CSD phase shifts are applied such that a device receiving the composite signal uses the third CSD phase shifts that correspond to the contiguous non-composite signal.

Abstract: A packet received by a network device is associated with a sequence number indicative of an order of transmission of the packet within a sequence of packets received by the network device. The network device determines whether the sequence number associated with the packet meets a first condition or a second condition for determining whether the packet is a duplicate of at least one other packet previously received by the network device. In response to determining that the sequence number meets the first condition, the network device deterministically determines whether the packet is a duplicate based on a record of previously received sequence numbers stored in a memory of the network device. In response to determining that the sequence number meets the second condition, the network device probabilistically determines whether the packet is a duplicate based on historical data maintained by the network device.
