This paper describes an architecture in which four GMSK modulated signals are combined in the digital domain. This saves a large number of analog components, many of which require production tuning. Consequently, an expensive and tedious part of manufacturing is eliminated. The proposed multicarrier GMSK modulator does

There are several small devices that could add value by having wireless radio connection to a mobile terminal but cannot bear the power consumption and cost associated with Bluetooth. However, mobile terminals are scheduled to have Bluetooth as the short-range wireless solution. LEE tackles the mismatch

Obviously, there are a number of small-sized devices that could add value by having wireless radio connection to mobile terminal but cannot bear the power consumption and cost associated to Bluetooth. LEE introduces minor additions to the Bluetooth chip in mobile terminals in order to allow major savings in power consumption and cost in the radios embedded into small devices such as wireless sensors and terminal enhancements. This paper presents the principles of LEE radio protocol, addresses the system capacity and elaborates the protocol implementation

Even so that wireless LAN (e.g. IEEE 802.11b) and Bluetooth solutions operating at the 2.4 GHz ISM band can be found in the same device. This enables new kind of usage possibilities and applications from which the most challenging ones, from interoperability point of view,

A novel functional nonlinear high power amplifier model for radio communication system simulation... more A novel functional nonlinear high power amplifier model for radio communication system simulations is used to study spectrum regeneration of a nonlinearly amplified π/4-DQPSK signal. Simulated adjacent channel power has been compared to measured results, and a very good resemblance is found. This together with a satisfactory intermodulation behaviour in a two-tone test simulation verifies that the proposed model is
