— Joint detection based on exploiting differences among the channels employed by several users allows a receiver to distinguish cochannel signals without reliance on spectrum spreading. This paper makes a number of new contributions to the topic: it provides an analytical expression for the union bound on average symbol-error rate for an arbitrary number of(More)
— Estimation of the channel impulse responses of multiple cochannel users is a key requirement of all multiuser detection and interference cancellation techniques, though little attention has been paid to subject in the context of TDMA systems. This paper addresses a pilot-based technique for multiuser channel estimation in a TDMA system, and makes several(More)
The aim of this study is to evaluate the efficacy of bilateral thoracoscopic sympathectomy in alleviating symptoms and improving quality of life in patients with hyperhidrosis or facial blushing and to investigate the occurrence, severity and possible underlying factors to compensatory sweating after surgery. One hundred and sixty-three patients in a single(More)
A quantitative morphological investigation of eight endocrine cell types in mucosal biopsies from adults with untreated celiac sprue was undertaken. The quantitative data expressed as cells per millimeter of epithelium most accurately reflected the changes seen in celiac disease, as it takes into account changes in mucosal thickness due to the absence of(More)
Fractures of the proximal third of the ulna and radius with associated anterior radial head dislocation are uncommon in children. Early recognition and appropriate management are essential to prevent long-term consequences of loss of forearm rotation, cubitus valgus, elbow instability and chronic pain. We present the case of a 3-year-old Caucasian boy who(More)
— In this paper we consider a generalization of the per-antenna-rate-control (PARC) MIMO scheme for the HSDPA option of WCDMA. The scheme, called PARC-N , allows the number of transmitted data substreams N to be less than the number of transmit antennas M and selects the best N antennas for transmission. We investigate PARC-N specifically in frequency(More)
