Abstract: 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.

Abstract: 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 maste r transceiver during each hop interval used by the strongest interfering maste r transceiver cannot interfere with the transmission of the first master transceiver during more than one hop interval of the first master transceive r, thereby minimizing the probability of self-interference between the first wireless network and the one of the neighboring wireless networks.

Abstract: "método e aparelho para minimizar a probabilidade de auto-interferência entre redes sem pio vizinhas". primeiro transceptor mestre (102) de uma primeira rede sem fio monitora (602) as redes sem fio vizinhas para descobrir o transceptor mestre interferidor mais forte em uma das redes sem fio vizinhas. o primeiro transceptor mestre então alinha no tempo (604) os intervalos de salto do primeiro transceptor mestre com os intervalos de salto do transceptor mestre interferidor mais forte para assegurar que a transmissor do transceptor mestre interferidor mais forte não pode interferir com a transmissão do primeiro transceptor mestre durante mais de um intervalo de salto do primeiro transceptor mestre, assim minimizando a probabilidade de auto-interferência entre a primeira rede sem fio e uma das redes sem fio vizinhas.

Abstract: A digital sync signal (502) is transmitted (702) from K transmitters (206) of a cluster (402), followed by K fine tuning signals (506) during K time slots (510), each time slot assigned to a transmitter. Each fine tuning signal comprises a pair of tones (512) separated in frequency by a predetermined amount. A portable subscriber unit (122) receives (706) the sync signal and the fine tuning signals, and makes (708) a rough estimate of the beginning of the fine tuning signals from the sync signal and from knowledge about the time slots. The portable subscriber unit computes (710) for each time slot a 2M-point Fourier transform (FT) on a received signal including M fine tuning signals received during the time slot from a transmitter of the cluster and from M-1 corresponding transmitters of adjacent clusters (404). The portable subscriber unit then fine tunes (722) the rough estimate through FT calculations.
