Urban Microcell MIMO Channel Path Data from Helsinki

Helsinki, Finland, is the location for this processed dataset of plane-wave propagation paths from a wideband MIMO channel sounding measurement at 5.3 GHz, conducted in April 2004. It contains direction of departure, direction of arrival, delay, and complex polarimetric path gain for the 30 strongest paths at each of 4,574 receiver locations along a 50-meter urban street route. The data is intended for the statistical comparison of receiver antenna performance in a realistic microcell environment.

Use Cases

• Statistical comparison of RX antenna performance based on direction of arrival and polarimetric gain data.
• Development and validation of geometric channel models using direction of departure, direction of arrival, and delay parameters.
• Analysis of multipath propagation characteristics in an urban street canyon scenario.
• Research into polarimetric MIMO channel properties using the 2x2 complex path gain matrix.

Strengths

• Contains a substantial number of measurement points with 4,574 receiver locations.
• Provides detailed per-path parameters including polarimetric information for the 30 strongest paths at each location.
• Based on a real-world measurement campaign in a defined urban environment (downtown Helsinki).

Limitations

• Exact receiver location coordinates for each channel measurement were not recorded.
• The complex path gain is not calibrated, limiting absolute power level analysis.
• Metadata completeness is low, with no column names, row counts, or specific update dates provided across sources.
