uture wireless multimedia terminals will have a variety of applications that require speech recognition capabilities. In this paper, we consider a robust distributed speech recognition system where representative parameters of the speech signal are extracted at the wireless terminal and transmitted to a centralized automatic speech recognition (ASR) server.(More)
In an asynchronous DS-CDMA system of multiple users where the orthogonality of spreading codes is broken, both uplink and downlink receptions face inter-symbol interference (ISI) and multiple access interference (MAI). Compared to traditional receiver techniques which require channel state information (CSI) and spreading codes, detection via blind source(More)
Satellite communications on-the-move systems that operate at the Ku-band (11-14 GHz band) and higher frequencies play a significant role in military and civilian communication systems. In order to limit interference to adjacent satellites, regulatory and standards bodies have established strict limits on the effective isotropic radiated power (EIRP) at a(More)
