摘要： Methods, apparatus and articles of manufacture for single antenna interference cancellation in a mobile communication system are disclosed. An example method disclosed herein for a wireless device comprises determining a number of bursts to be received in a time division multiple access frame comprising a plurality of timeslots, and when the number of bursts exceeds a threshold number of bursts for which single antenna interference cancellation can be performed, performing single antenna interference cancellation for a subset of the bursts received in the time division multiple access frame.

摘要： Methods and systems for slow associated control channel signaling are disclosed. An example method for securing communications in a mobile network disclosed herein comprises transmitting a first variant of a message of a first type on a first slow associated control channel (SACCH) before ciphering is started on the first SACCH, and after ciphering is started on the first SACCH, transmitting a second variant of the message of the first type on the first SACCH, and subsequently transmitting the second variant of the message of the first type on the first SACCH, wherein the subsequently transmitted second variant of the message of the first type is the next transmitted message of the first type on the first SACCH.

摘要： A method and transmitter, the method generating a burst containing a first data portion and a second data portion surrounding a training sequence; and appending to the burst a cyclic prefix and a cyclic postfix. Further a receiver on a network element, the receiver configured to: receive a burst containing a cyclic prefix, a cyclic postfix and a data portion; remove at least one of the cyclic prefix or the cyclic postfix; transform the data portion with a discrete Fourier transform; estimate the channel frequency response and modulation of the burst; undo an effect of a channel on the data portion by using the estimated channel frequency response of the channel on the transformed data; use an inverse discrete Fourier transform on the result of the equalizing step; and further process the output of the equalization step to decode the transmitted bits.
