It should be noted that both approaches intend to extract conclusions at system level, using the link level as a source of information. The Viterbi algorithm is based on a recursion over the accumulated Euclidean Distance for each of the 16 equaliser states. The latter has twice higher bit rate but is more prone to errors due to interference and noise hence it requires stronger forward error correction (FEC) coding which in turn means Full-text · Article · Oct 2002 Javier GozalvezJohn DunlopRead full-textBit error rate characterisation and modelling for GSM[Show abstract] [Hide abstract] ABSTRACT: This paper presents a method to model the bit error

The air interface technology was Frequency Division Multiple Access (FDMA) and the modulation was analog FM, but with different deviations and channel spacings. The former shows thc distribution for BER values bigber than 0, i.e bursts with errors.

Dunlop, “Bit Error Rate Link Adaptation for GSM,” The 9th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Vol. 3, 8-11 September 1998, pp. 1530-1534. 被如下文章引用: TITLE: Performance Evaluation

On noisy channels HSDPA adapts to provide reliable communications using QPSK and 1/3 coding rate but the information bit rate drops to about 2.4 megabit/sec. The bit error rate is defined at the output of the burst dehuilder. For that purpose, a characterisation of the number of bit errors per burst is carried out for a numbcr of scenarios, and the results extracted are used to implement a model Your cache administrator is webmaster.

To increase the data rate we have to utilize the full channel based on the channel condition.

In poor link conditions all redundant bits are transmitted and the information bit rate drops. When the radio link conditions are good more bits are punctured and the information bit rate is increased. The performance of a bit rate based link adaptation algorithm is assessed in [7].

A method to obtain results for any carrier to interference ratio and speed is then proposed, based on linear interpolation. The results are compared to the output of full transmission chain simulation, showing that a good degree of accuracy is achieved, while the simulation time s drastically reduced. GMSK modulation is applied. The latter shows the evolution of the probability of having a burst without any errors.

The correlator produces a channel estimate using the knowledge of the training sequence bits. the pathloss, the interference due to signals coming from other transmitters, the sensitivity of the receiver, the available transmitter power margin, etc.).
