摘要： A method for reducing a signal-to-noise ratio requirement in a time division multiple access (TDMA) link of a mobile network. The network includes a first node and a second node. The method includes receiving at the first node, an initial TDMA signal burst transmitted from the second node, the initial burst comprising a long preamble and determining link state variables, thereby synchronizing the first node to the TDMA signal burst. The method further includes tracking the link state variables between the initial TDMA signal burst and subsequent receptions of TDMA signal bursts from the second node at the first node the subsequent burst comprising a short preamble. The link variables mainly comprise synchronisation parameters.

摘要： Multiplexing is prepared for a new user by shortening the transmission timing intervals of connected users in a time slot of low multiplicity. Contrarily, multiplexing is not prepared for a new user by maintaining the transmission timing intervals of connected users as much as possible in a time slot of high multiplicity. As a result, it is possible to set up a preparation slot for a new user while maintaining the transmission timing intervals as wide as possible. Degradation of the characteristics is prevented since the transmission timing intervals of connected users in a telephone channel are maintained as much as possible. The shift of the transmission timing for a new user is performed during a control channel period, and therefore most suitable transmission timing intervals are realized when a telephone channel is set up. These processings are carried out by a DSP (l4).
摘要翻译：通过缩短连接用户在低倍数时隙的传输定时间隔来为新用户准备复用。相反，通过在高多重性的时隙中尽可能多地维护连接的用户的传输定时间隔，不能为新用户准备多路复用。结果，可以在保持尽可能宽的传输定时间隔的同时为新用户设置准备时隙。由于电话通道中的连接用户的发送定时间隔尽可能地被保持，所以防止了特性的劣化。在控制信道周期期间执行新用户的发送定时的移位，因此在建立电话信道时实现最适合的发送定时间隔。这些处理由DSP（14）执行。

摘要： A wireless network is provided that uses pseudo-static time slots. These time slots remain fixed in time unless and until a network controller specifically changes them and the network controller subsequently receives confirmation of the change. Times and durations of the pseudo-static time slots are only changed in small steps as each relevant device in the network acknowledges the step. To aid in allowing full coverage even during a change of active devices, when a transmitter and receiver are moved to a new time slot, the receiver is set to listen to both the old and the new time slots until the transmitter confirms that is has made the switch.

摘要： A multiple access digital communication method in ultra-wideband (UWB) radio access network is provided. More specifically, a multiple access technique in UWB communication channels is provided where UWB communication channels can be more efficiently used and collisions between multiple access user nodes can be more effectively avoided when the channels have a great multiple path fading. The digital communication method for use in an uplink in a UWB communication system includes the steps of: receiving data symbols from respective nodes, in which the data symbols are transmitted according to respective orthogonal time hopping patterns; checking whether there is a collision of the orthogonal time hopping patterns; and decoding the data symbols depending on whether data symbols of nodes involved in the collision of the orthogonal time hopping patterns are the same.

摘要： The invention provides improved suppression of co-channel interference (CCI) in a wireless cellular communications system where at least two base stations use the same transmit frequency. The method according to the invention uses the difference in synchronisation times between the home signal and the CCI signal to suppress the CCI signal. The method uses a modified known method of estimating time of arrival (TOA) to estimate sync positions for the CCI signal. This enables the use of interference cancelling methods in communications systems using un-synchronised base stations. Receiver performance is improved, which in turn improves data throughput and received speech quality, since interfering signals from base stations using the same frequency can be suppressed.

摘要： The aim of the invention is to adapt the timing advance of a mobile terminal (MS) during synchronous handover from a first (BS1) to a second base station (BS2) of a radio communications system. To this end a time delay ( DELTA t, DELTA ta, DELTA td) between time standard (N1, 2, N2a, N2d) received by the terminal from the two base stations are measured. A timing advance value (TA1) that is used by the terminal (MS) prior to handover for transmission to the first base station (BS1) is corrected using the time delay measured. The corrected timing advance value is reduced by a value (2Gsync) derived from the accuracy (Gsync) of the synchronicity of the two base stations (BS1, BS2) and is used as the timing advance value (TA2) for transmission to the second base station (BS2).
