Methods, systems, and apparatuses are presented for improved satellite communications. The satellite system may comprises at least one gateway, a satellite in orbit configured to communicate with the at least one gateway and provide a plurality of spot beams, and a plurality of subscriber terminals. The spot beams may include a first spot beam to illuminate a first region and a second spot beam to illuminate a second region adjacent to and overlapping with the first region. The first spot beam as sent to at least one subscriber terminal may be affected by (1) interference from other signal sources including the second spot beam at a signal-to-interference ratio C / I and (2) noise at a signal-to-noise ratio C / N. Reception of signals from the first spot beam by the at least one of the first plurality of subscriber terminals may be interference-dominated such that C / I is less than C / N.

A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.

A high capacity, continuous production blast freezer includes an insulated enclosure and a plurality of adjustable product-carrying trolleys, individually moveable with the enclosure from an entrance location to an exit location. A heat exchanger in the form of an evaporator is provided in the enclosure. The mechanical equipment for the refrigeration system can be placed within the enclosure and separated from the freezing cell by a bulkhead. In one embodiment the enclosure is in the form of a container adapted to be transportable by ship, rail or truck. The arrangement of the heat exchanger or evaporator relative to the product carrying devices and the enclosure is designed to maximize the capacity of the heat exchanger and minimize frost formation, while providing for a maximum amount of product space within the enclosure to maximize throughput of the system.

The invention provides a new method and system for low complexity, low cost, small component size, and low power communications. The system provides a digital sub-sampling receiver for multiple-antenna wireless receivers, with reduced number of analog RF / IF chains (or one chain) after a fixed number of receive antennas. The system provides a generator of transmit signals / sequences which are preconditioned by the operation of the system to compensate for spectral effects of ultra-low-rate sub-sampling, in that sequences preserve orthogonality under spectral repetition, spectral translation and spectral inversion. The system provides a management device to provide adaptation in transmit signals / waveforms / patterns as a function of channel and data source variations, such that communication data rates and capacities are maximized. The system can efficiently operate in multi-user multi-channel communication systems. The method implemented by the invention is split in its operation across the transmitter of the transmitting device and the receiver of the receiving device.

A novel and useful adaptive frequency hopping scheme for wireless devices and networks operating in a congested environment of similar devices, where capacity maximization is desired. The hopping sequence of each wireless link is dynamically adapted such that the impact of the surrounding interference is minimized and the interference induced onto the coexisting systems is also minimized. The scheme detects the repetitive presence of interference on a particular channel and comprises a replacement mechanism for swapping the interfered frequency-channel with one that would be clear for that particular time-slot. The mechanism detects interference during a redundant portion of the transmission (i.e. header or trailer) without having to experience packet failures (i.e. data loss). If the interference impact (e.g. corrupted header bits) exceeds a predefined threshold, that frequency channel is declared temporarily unusable for that time slot and is replaced with another in accordance with a frequency replacement policy. Periodic interference at a particular frequency, originating from a coexisting system of similar operating parameters, may also be detected at instances that are distant from the timeslots for which that particular frequency is to be used, such that frequency replacement in the hopping sequence can be scheduled ahead of time and collisions would be avoided altogether.
