摘要： A radio communication system (100) implements a frequency reuse plan by sending a message (308) simultaneously with other messages in a plurality of cell clusters (202-208) utilizing the frequency reuse plan, which provides a message carrier-to-interference ratio (C/I) sufficient for reception of the message when a receiver (104) is adjusted in accordance with a periodically transmitted pilot symbol (402-408). The C/I is smaller than preferred for reception of the pilot symbol. The pilot symbol is periodically transmitting simultaneously with other pilot symbols in a time diverse manner such that pilot symbol transmissions for adjacent ones of the plurality of cell clusters occur in non-overlapping time slots, thereby generating the larger C/I preferred for reception of the pilot symbol. The pilot symbol and the message are received by the receiver, and the receiver is adjusted in accordance with the pilot symbol to demodulate the message.

摘要： A receiver (109) and a method therein arranged and constructed to receive a signal using a noncoherent matched filter structure including a frequency detector (205) arranged to process a first portion (602) of the signal to provide a frequency error; a timing detector (206), responsive to the frequency error, arranged to process a second portion (604) of the signal to provide a timing error; and a symbol detector (209), responsive to the frequency error and the timing error, arranged to process a symbol portion (606) of the signal to provide a detected symbol.

摘要： A first master transceiver (102) of a first wireless network monitors (602) neighboring wireless networks to discover a strongest interfering master transceiver in one of the neighboring wireless networks. The first master transceiver then time-aligns (604) hop intervals of the first master transceiver with the hop intervals of the strongest interfering master transceiver to ensure that a transmission of the strongest interfering master transceiver during each hop interval used by the strongest interfering master transceiver cannot interfere with the transmission of the first master transceiver during more than one hop interval of the first master transceiver, thereby minimizing the probability of self-interference between the first wireless network and the one of the neighboring wireless networks.
