    Abstract: A method and apparatus for producing an estimate of the acoustic response an environment. The method comprises receiving a first signal, and a second signal including a part of the first signal. The first and second signals are combined to produce a third signal. The first signal is combined with itself to produce a fourth signal. A plurality of weighted means of said third signal are computed and summed to produce a plurality of first summations. A plurality of weighted means of said fourth signal are computed and summed to produce a plurality of second summations. Said estimate is generated from said first and second summations.

    Abstract: This invention relates to radio communication networks and more particularly, but not exclusively, to radio communication networks using multiple access techniques. A system and method for adaptively changing the characteristics of a signal transmitted across a network is provided. In one embodiment, the communications network comprises at least two stations for transmitting and receiving; wherein at least one of the stations is capable of sending a control signal to the other station after receiving a signal transmitted over the network from the other station after analysis of the transmitted signal, which control signal is transmitted as a data packet independent of the other data and overhead signals.

    Abstract: This invention relates to radio communications and in particular relates to a method for allocating channels in a radio communications system having a plurality of bearers in a system which is subject to slow temporal fading. In radio communications, signals are transmitted at a particular frequency, in a frequency band or in a number of frequency bands. Obstacles in a signal path, such as buildings in built-up areas and hills in rural areas, act as signal scatterers and these, together with fading, amongst other factors can cause signalling problems whereby signals may not be communicated on certain channel The present invention provides a system and method for channel allocation method for a multi-bearer communications network, with each bearer supporting a number of channels, wherein after allocation of a channel responsive to an access request from the available bearers which can provide access, the maximum number of available slots are left on each bearer, for a particular level of subscription.

    Abstract: This invention relates to duplex and to half duplex transmission schemes and more particularly to the application of such schemes in TDMA and other multiple access environments. In accordance with a first aspect of the invention, there is provided a method of multiplexing signals transmitted by a number of terminals onto a communications link; the link having a capacity less than the total capacity of the terminals; the method including the step of varying the rate of encoding of said signals transmitted by said terminals whereby the bandwidth o the transmitted signals corresponds to the portions allocated to the terminals. In accordance with another aspect of the invention, there is provided a system for the communication of signals in real time over a channel; said system adapted to vary the bandwidth of at least one signal such that the number of signals multiplexed onto said channel can be dynamically varied.
