A communications terminal receives a data communications signal via a random access channel. A processor searches for data bursts in a first time-slot that include one of a first set of signature sequences assigned to the first time-slot. When a data burst A in the first time-slot includes one of the first set of signature sequences, the data burst A in the first time-slot is an initial burst of a message from a first communications terminal. The processor determines whether a second time-slot includes a data burst B that includes the one signature sequence. When the second time-slot includes the data burst B, the message is a multi-burst message and that the data burst B is a second burst of the multi-burst message. When the second time-slot does not include the data burst B the message is a single-burst message that has been completed via the first time-slot.

An exemplary wireless communication network that includes a base that communicates with remote units located in a cell of the network. The base concatenates information symbols with a preamble corresponding to a destination remote unit. One or more remote units communicating with the base each concatenates information symbols with a preamble corresponding to that remote unit. An adaptive receiver system for a base unit rapidly adapts optimal despreading weights for reproducing information symbols transmitted from multiple remote units. A transmitter system for a base unit concatenates information symbols with a preamble associated with a remote unit in the cell. An adaptive receiver system for a remote unit in a communication network rapidly adapts optimal weights for reproducing a signal transmitted to it by a specific base unit in the network.

A method and a communication receiver have been described for calculating log-likelihood ratios in a communication receiver. The log-likelihood ratio is calculated for each bit of one or more subsymbols of each of the one or more spatial streams by computing effective noise on one or more spatial streams after considering noise terms resulting from MIMO detection estimates of the subsymbols on each spatial stream. Finally, signal to noise ratio is determined for one or more spatial streams from the effective noise and scaling bit log-likelihood ratios with the signal to noise ratio.

A multi-mode receiver includes a channel decomposition module (e.g., a Rake receiver) for separating a received signal into multipath components, an interference selector for selecting interfering paths and subchannels, a synthesizer for synthesizing interference signals from selected sub channel symbol estimates, and an interference canceller for cancelling selected interference in the received signal. At least one of the channel decomposition module, the synthesizer, and the interference canceller are configurable for processing multi-mode signals.
