摘要： Methods and devices for receiving or transmitting a wireless packet are described. A wireless packet includes a short training field (STF) and a channel estimation field (CEF). The receiver determines whether the received STF matches an assigned STF assigned for a target link, by performing cross-correlation between the STF and a component sequence from a set of at least four different component sequences which are pairs of Golay sequences. The cross-correlation output is compared with an expected output. When the received STF matches the assigned STF, the wireless packet is considered a target packet. A channel estimation is performed using a cross-correlation of the received CEF with an assigned CEF assigned for the target link. The assigned CEF is from a set of two or more CEFs, where each CEF is formed using the set of component sequences, and the CEFs are pairwise zero-correlation zone (ZCZ) sequences.

摘要： The present disclosure provides for the construction and use of a set of Zero-Correlation-Zone (ZCZ) Concatenated Complementary Pair (CCP) sequences with zero-correlation-zone range greater than one or with zero-correlation-zone range equal to one and the sequence set size greater than two. Complementary pair sequences A and B are selected and, for each member of the set of ZCZ CCP sequences, sign sequences pA and pB are combined with the complementary pair sequences to form a member ZCZ CCP sequence of the set. A ZCZ CCP sequence modified by propagation over a communication channel may be identified by cross-correlation with ZCZ CCP sequences of the set. A set of sign sequences may be constructed by recursive expansion from an initial set or found by a computer search. The sequences may be used in a transceiver of a portable electronic device or other communication device.

摘要： The present document relates to the transmission of data in a digital cellular telecommunications network. In particular, the present document relates to the secure transmission of data over Global System for Mobile Communications (GSM) networks. A method for encoding a SACCH information block in a wireless network is described. The method comprises randomizing a plurality of randomization unit input bits derived from at least some of a plurality of payload bits of the SACCH information block using a pseudo-random bit block, thereby yielding a plurality of randomized bits; and ciphering a plurality of ciphering unit input bits derived from at least some of the plurality of randomized bits, thereby yielding an encoded data burst of a SACCH frame; wherein ciphering is based on a ciphering algorithm using a ciphering key Kc and a frame number COUNT of the SACCH frame; wherein the pseudo-random bit block is determined based on the ciphering key Kc.
