| Description | In order to study the symbol timing sensitivity of symbol-spaced trellis-based equalizers, the following three criteria are evaluated as a function of the sampling phase: (i) The so-called RAKE receiver bound for signaling on a frequency-selective fading channel (which is related to the matched filter bound), (ii) the average power of the taps of the equivalent discrete-time channel model, and (iii) the bit error rate for symbol-spaced maximum-likelihood sequence estimation (MLSE). The timing sensitivity depends on the pulse shaping and the channel model. For rectangular pulses, a difference of up to about 5 dB between taking the worst and best sampling phase within a symbol period is observed. For bandlimited pulses, however, there may be no practical need for a clock recovery loop or for using fractionally-spaced MLSE. in Proc. IEEE GLOBECOM'98 |
