Rapid growth of data services in wireless communication systems requires an efficient means for high speed data transport. Modern CDMA systems have evolved to support this need. This paper presents an overview of the key techniques for improving high speed data transport in the following standards: 1xEV-DO (IS-856 Rev A), 1xEV-DV (cdma2000 Rev D), and HSDPA(More)
Simultaneous communications over parallel channels is a prominent scheme in modern wireless system. Intuitive multi-channel solution allocates one independent RF chain (including LNA, low-noise amplifier) to each separate channel, causing high implementation cost. Alternatively, low-cost RF uses one single LNA to cover all parallel channels and save(More)
