An Automatic Link Establishment (ALE) system incorporating Avalanche Relay (AR) is disclosed. The system includes a plurality of network nodes such as a calling node, one or more intermediate nodes, and a responding node. The calling node transmits a link establishment message to the responding node through one or more intermediate nodes. The message is transmitted via one or more transmitting and receiving channels. The one or more intermediate nodes relay the message to the responding node or one or more different intermediate nodes. The responding node receives the message and responds back to the calling node through the one or more intermediate nodes. The message may be transmitted via the same one or more channels used to receive the message.

A method of routing a first signal in a telecommunication network is disclosed. The telecommunication network comprises plural nodes and uses time-division multiple access (TDMA) frames, with each TDMA frame divided into time slots and each time slot is divided into subslots. The method includes the step of transmitting a first signal from an initiating node in a first subslot. The method further includes the step of receiving the first signal at other nodes in the network in the first subslot, wherein the first signal is retransmitted in a second subslot subsequent to the first subslot. An improvement in the method includes the step of preparing for the retransmission at least one of a time-dispersed first signal or time-dispersed algorithmically related first signal by two or more nodes via a controller.

Relays in structured ad hoc networks

Optimal GMSK training sequences are generated by applying a base sequence to the in-phase component of the even samples and rotating the base sequence by 2and applying the second sequence to the quadrature component of the odd samples. Using the optimal GMSK training sequence a channel estimate can be generated. Filtering the channel estimate converts the channel impulse response to one that can be used with a non-GMSK signal e.g. PSK or QAM.

Converting GMSK impulse responses and optimal sequences

A radio receiver system configured to remove click noise from a demodulated signal is disclosed. The radio receiver system may employ digital demodulation or analog demodulation. The radio receiver system may be configured to determine measures of a statistical distribution of amplitudes of the demodulated signal, and thresholds for limiting the demodulated signal based on the measures of the statistical distribution of amplitudes. Portions of the demodulated signal exceeding the thresholds are either soft limited or hard limited.
